  • Install Python 2.6 without using installer on Win32

    - by prosseek
    I need to run a python script on a machine that doesn't have python installed. What I did was as follows. Copy python.exe, python26.dll, msvcr90.dll and Microsoft.VC90.CRT.manifest zip all the directory in LIBs directory as the python26.zip copy all the necessary dll/pyd file inside the DLL directory. It seems to work, but when I change the python26.zip to the other name such as pythonlib.zip. It cannot find the python library anymore. Q1 : What's the magic behind the python26.zip name? The python automatically finds a library inside a python26.zip but not with different name? Q2 : If I have python26.zip at the same directory where python.exe/python26.dll is, I don't need to add path sys.path.append(THE PATH TO python26.zip). Is it correct?

    - by avon_verma
    I have a few questions about python I've seen many pages like these on Google http://mail.google.com/support/bin/answer.py?answer=6583 https://www.google.com/adsense/support/bin/topic.py?topic=13488 ...that have .py extensions. 1: Are pages like these built on pure python code, but printing out html like print "<div etc..." or like the typical asp,jsp,php type of pages with html pages and embedded python code like: <html> <% some python code %> </html> 2: What is python mainly used for making? windows apps or web or .. ? Also, are ruby and perl also similar to python?

  • Running python batch file that has a path with SPACE character

    - by prosseek
    The batch file is something like this, I put the python in some directory that has SPACE character in its path. C:\"Documents and Settings"\Administrator\Desktop\bracket\python\python C:\\"Documents and Settings"\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py When I run this one, I get this error. C:\Documents and Settings\Administrator\Desktop\bracket\python\python: can't ope n file 'C:\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\bra ckettest.py': [Errno 2] No such file or directory C:\Documents and Settings\Administrator\Desktop\bracket What might be wrong? Wrapping the path doesn't solve this problem. "C:\\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py" Are the brackets ('[]') cause of the problem? On Mac, python works well with bracket character.

  • Google Maps API v3 not working

    - by user1496322
    I've been banging my head on the wall after going through the documentation on this several times! I can't seem to get past the API error to get the map to appear on my site. I am getting the following error message from the web page where I want the map to be displayed: ~~~~~~~~~~~ Google has disabled use of the Maps API for this application. The provided key is not a valid Google API Key, or it is not authorized for the Google Maps Javascript API v3 on this site. If you are the owner of this application, you can learn about obtaining a valid key here: https://developers.google.com/maps/documentation/javascript/tutorial#Obtaining_Key ~~~~~~~~~~~ I have (several times now) gone into my account and 1) enabled the Maps v3 API service. 2) Generated a new API key. and 3) added my allowed referrers to the key. (both www.domain.com and domain.com URLs) I have the following added to the head of the web page: < script src="http://maps.googleapis.com/maps/api/js?sensor=false&key=MY_API_KEY_HERE" type="text/JavaScript" language="JavaScript" And... I have the following javascript function that executes when a link is clicked on the page: alert("viewMap()"); var map = new GMap3(document.getElementById("map_canvas")); var geocoder = new GClientGeocoder(); var address = "1600 Amphitheatre Parkway, Mountain View"; alert("Calling getLatLng ..."); geocoder.getLatLng(address, function(point) { var latitude = point.y; var longitude = point.x; // do something with the lat lng alert("Lat:"+latitude+" - Lng:"+longitude); }); The initial 'viewMap' alert is displayed and then is followed by the 'Google has disbled use...' error message. The error console is also showing 'GMap3 is not defined'. Can anyone please assist with showing me the errors of my ways?!?!? Thank you in advance for any help you can provide. -Dennis

  • NoSQL Memcached API for MySQL: Latest Updates

    - by Mat Keep
    With data volumes exploding, it is vital to be able to ingest and query data at high speed. For this reason, MySQL has implemented NoSQL interfaces directly to the InnoDB and MySQL Cluster (NDB) storage engines, which bypass the SQL layer completely. Without SQL parsing and optimization, Key-Value data can be written directly to MySQL tables up to 9x faster, while maintaining ACID guarantees. In addition, users can continue to run complex queries with SQL across the same data set, providing real-time analytics to the business or anonymizing sensitive data before loading to big data platforms such as Hadoop, while still maintaining all of the advantages of their existing relational database infrastructure. This and more is discussed in the latest Guide to MySQL and NoSQL where you can learn more about using the APIs to scale new generations of web, cloud, mobile and social applications on the world's most widely deployed open source database The native Memcached API is part of the MySQL 5.6 Release Candidate, and is already available in the GA release of MySQL Cluster. By using the ubiquitous Memcached API for writing and reading data, developers can preserve their investments in Memcached infrastructure by re-using existing Memcached clients, while also eliminating the need for application changes. Speed, when combined with flexibility, is essential in the world of growing data volumes and variability. Complementing NoSQL access, support for on-line DDL (Data Definition Language) operations in MySQL 5.6 and MySQL Cluster enables DevOps teams to dynamically update their database schema to accommodate rapidly changing requirements, such as the need to capture additional data generated by their applications. These changes can be made without database downtime. Using the Memcached interface, developers do not need to define a schema at all when using MySQL Cluster. Lets look a little more closely at the Memcached implementations for both InnoDB and MySQL Cluster. Memcached Implementation for InnoDB The Memcached API for InnoDB is previewed as part of the MySQL 5.6 Release Candidate. As illustrated in the following figure, Memcached for InnoDB is implemented via a Memcached daemon plug-in to the mysqld process, with the Memcached protocol mapped to the native InnoDB API. Figure 1: Memcached API Implementation for InnoDB With the Memcached daemon running in the same process space, users get very low latency access to their data while also leveraging the scalability enhancements delivered with InnoDB and a simple deployment and management model. Multiple web / application servers can remotely access the Memcached / InnoDB server to get direct access to a shared data set. With simultaneous SQL access, users can maintain all the advanced functionality offered by InnoDB including support for Foreign Keys, XA transactions and complex JOIN operations. Benchmarks demonstrate that the NoSQL Memcached API for InnoDB delivers up to 9x higher performance than the SQL interface when inserting new key/value pairs, with a single low-end commodity server supporting nearly 70,000 Transactions per Second. Figure 2: Over 9x Faster INSERT Operations The delivered performance demonstrates MySQL with the native Memcached NoSQL interface is well suited for high-speed inserts with the added assurance of transactional guarantees. You can check out the latest Memcached / InnoDB developments and benchmarks here You can learn how to configure the Memcached API for InnoDB here Memcached Implementation for MySQL Cluster Memcached API support for MySQL Cluster was introduced with General Availability (GA) of the 7.2 release, and joins an extensive range of NoSQL interfaces that are already available for MySQL Cluster Like Memcached, MySQL Cluster provides a distributed hash table with in-memory performance. MySQL Cluster extends Memcached functionality by adding support for write-intensive workloads, a full relational model with ACID compliance (including persistence), rich query support, auto-sharding and 99.999% availability, with extensive management and monitoring capabilities. All writes are committed directly to MySQL Cluster, eliminating cache invalidation and the overhead of data consistency checking to ensure complete synchronization between the database and cache. Figure 3: Memcached API Implementation with MySQL Cluster Implementation is simple: 1. The application sends reads and writes to the Memcached process (using the standard Memcached API). 2. This invokes the Memcached Driver for NDB (which is part of the same process) 3. The NDB API is called, providing for very quick access to the data held in MySQL Cluster’s data nodes. The solution has been designed to be very flexible, allowing the application architect to find a configuration that best fits their needs. It is possible to co-locate the Memcached API in either the data nodes or application nodes, or alternatively within a dedicated Memcached layer. The benefit of this flexible approach to deployment is that users can configure behavior on a per-key-prefix basis (through tables in MySQL Cluster) and the application doesn’t have to care – it just uses the Memcached API and relies on the software to store data in the right place(s) and to keep everything synchronized. Using Memcached for Schema-less Data By default, every Key / Value is written to the same table with each Key / Value pair stored in a single row – thus allowing schema-less data storage. Alternatively, the developer can define a key-prefix so that each value is linked to a pre-defined column in a specific table. Of course if the application needs to access the same data through SQL then developers can map key prefixes to existing table columns, enabling Memcached access to schema-structured data already stored in MySQL Cluster. Conclusion Download the Guide to MySQL and NoSQL to learn more about NoSQL APIs and how you can use them to scale new generations of web, cloud, mobile and social applications on the world's most widely deployed open source database See how to build a social app with MySQL Cluster and the Memcached API from our on-demand webinar or take a look at the docs Don't hesitate to use the comments section below for any questions you may have

  • Which Python Framework and CMS coming from PHP - Codeigniter+ExpresionEngine?

    - by Joshua Fricke
    We are currently developing most of our applications in PHP using CodeIgniter (CI) and ExpressionEngine (EE) and are looking to try our hands at Python. So we are looking for a Framework and ideally a CMS that work well together like the CI+EE combo does. Have done a bit of research, it looks like these are some good suggestions (though we are not limiting to these): Frameworks - http://wiki.python.org/moin/WebFrameworks Django Web2py CMS - http://wiki.python.org/moin/ContentManagementSystems Below picked because they are developed with a Framework (my only frame of reference using CI+EE) Merengue Mezzanine Django CMS Input would be great in helping us decide.

  • Is Python worth learning? Is it a useful tool? [closed]

    - by Kenneth
    I recently had a discussion with a professor of mine on the topic of web development. I had recently decided I would learn python to increase my arsenal of web tools which I mentioned to him at that time. He almost immediately asked why I would waste my time on that. I'm not certain but I think he recently started in on researching and studying web development so he could pick up the web development classes that haven't been taught for a while after the previous professor who taught those classes left. I've heard a lot about python and thought maybe he was mistaken about its usefulness. Is python a useful tool to have? What applications can it be used for? Is it better than other similar alternatives? Does it have useful applications outside of web development as well?

  • Is there any one standard framework for developing Python GUI apps.?

    - by RPK
    There are so many frameworks for writing GUI application using Python. But is there any one key standard framework? For example we have a bundle of .NET/C# on Visual Studio. I am thinking in other perspectives also. In future if I give an interview for a Python programmer job, which GUI framework will be considered? I also wonder, there is no IDE that integrates the GUI and Python language. Choice of flavor is good but over-choice becomes a distraction.

I have tried everything, setting it back to python.exe does not work, I even went to Control Panel to see if it could help, but Control Panel couldn't help either. So if someone could help me please that would be great. Thank you.

  • Why should I install Python packages into `~/.local`?

    - by Matthew Rankin
    Background I don't develop using OS X's system provided Python versions (on OS X 10.6 that's Python 2.5.4 and 2.6.1). I don't install anything in the site-packages directory for the OS provided versions of Python. (The only exception is Mercurial installed from a binary package, which installs two packages in the Python 2.6.1 site-packages directory.) I installed three versions of Python, all using the Mac OS X installer disk image: Python 2.6.6 Python 2.7 Python 3.1.2 I don't like polluting the site-packages directory for my Python installations. So I only install the following five base packages in the site-packages directory. For the actual method/commands used to install these, see SO Question 4324558. setuptools/ez_setup distribute pip virtualenv virtualenvwrapper All other packages are installed in virtualenvs. I am the only user of this MacBook. Questions Given the above background, why should I install the five base packages in ~/.local? Since I'm installing these base packages into the site-packages directories of Python distributions that I've installed, I'm isolated from the OS X's Python distributions. Using this method, should I be concerned about Glyph's comment that other things could potentially break (see his comment below)? Again, I'm only interested in where to install those five base packages. Related Questions/Info I'm asking because of Glyph's comment to my answer to SO question 4314376, which stated: NO. NEVER EVER do sudo python setup.py install whatever. Write a ~/.pydistutils.cfg that puts your pip installation into ~/.local or something. Especially files named ez_setup.py tend to suck down newer versions of things like setuptools and easy_install, which can potentially break other things on your operating system. Previously, I asked What's the proper way to install pip, virtualenv, and distribute for Python?. However, no one answered the "why" of using ~/.local.

  • What is missing from the Java API?

    - by Jack
    I started using Java years ago and I've always found almost everything I need inside the standard API provided with JDK SE, with the exception of specific things that don't fit well inside a generic API, like GUI elements (graphs or so on) or advanced mathematical API.. So I was wondering: Which are the most important things that the Java API is missing? When I say "important", I mean either things that you have often needed, but have had to rely on custom libraries, or things that are usually are included in APIs, but not in Java's.

  • PHP - JSON Steam API query

    - by Hunter
    First time using "JSON" and I've just been working away at my dissertation and I'm integrating a few features from the steam API.. now I'm a little bit confused as to how to create arrays. function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530'); $test = decode_url($api); var_dump($test['response']['players'][0]['personaname']['steamid']); } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $data = file_get_contents($url); $data_output = json_decode($data, true); return $data_output; } So ea I've wrote a simple method to decode Json as I'll be doing a fair bit.. But just wondering the best way to print out arrays.. I can't for the life of me get it to print more than 1 element without it retunring an error e.g. Warning: Illegal string offset 'steamid' in /opt/lampp/htdocs/lan/lan-includes/scripts/class.steam.php on line 48 string(1) "R" So I can print one element, and if I add another it returns errors. EDIT -- Thanks for help, So this was my solution: function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530,76561197960435530'); $data = decode_url($api); foreach($data ['response']['players'] as $player) { echo "Steam id:" . $player['steamid'] . "\n"; echo "Community visibility :" . $player['communityvisibilitystate'] . "\n"; echo "Player profile" . $player['profileurl'] ."\n"; } } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $json = file_get_contents($decodeURL); $data_output = json_decode($json, true); return $data_output; } Worked this out by taking a look at the data.. and a couple json examples, this returns an array based on the Steam API URL (It works for multiple queries.... just FYI) and you can insert loops inside for items etc.. (if anyone searches for this).

  • Twitter api and retweets

    I'm trying to get the last tweet from the people I follow using the twitter api (http://api.twitter.com/1/statuses/friends.json&screen_name=[username]), but I noticed that if the user's last tweet is a retweet, the json data does not contain a "status" element. Using the "user timeline" api does not work either, the last tweet is the last non retweeted tweet. Is there a way to get the real last status, even if it's a RT, through the twitter API?
