  • String literals in python

    - by kjakeb
    Hello, Is there a way to declare a string variable in python such that everything inside of it is automatically escaped, or has its literal character value? I'm NOT asking how to escape the quotes with slashes, that's obvious. What I'm asking for is a general purpose way for making EVERYTHING in a string literal so that I don't have to manually go through and escape everything for very large strings. Anyone know of a solution? Thanks!

  • Why does this python code work?

    - by Int-0
    I have written a simple python module, it has this code: _log = logging.getLogger("mymodule") _started = False def set_log_level(level): _log.setLevel(level) if not _started: _hdlr = logging.FileHandler('mymodule.log') When I call set_log_level() program fails because symbol _started is not found. It is normal because global _started is missing in the method. But my question is: symbol _log has the same visibility as _started, so why does this symbol can be found? BR, // Toby

  • Exact cin equivalent function in python

    - by gkt.pro
    Suppose user enter this string at terminal 123 456 456 //then hit enter How do I scan these three (could be more) numbers in different variables in python Could be something like this: for i in range(1,n) m[i]=#WHAT FUNCTION SHOULD I PUT HERE In c++ we can easily use cin>>m[i] inside above loop to scan the variables. If i use input() or raw_input() , they would scan whole line in single variable.

  • Pure python implementation of greenlet API

    - by Tristan
    The greenlet package is used by gevent and eventlet for asynchronous IO. It is written as a C-extension and therefore doesn't work with Jython or IronPython. If performance is of no concern, what is the easiest approach to implementing the greenlet API in pure Python. A simple example: def test1(): print 12 gr2.switch() print 34 def test2(): print 56 gr1.switch() print 78 gr1 = greenlet(test1) gr2 = greenlet(test2) gr1.switch() Should print 12, 56, 34 (and not 78).

  • Find Hyperlinks in Text using Python (twitter related)

    - by TimLeung
    How can I parse text and find all instances of hyperlinks with a string? The hyperlink will not be in the html format of <a href="http://test.com">test</a> but just http://test.com Secondly, I would like to then convert the original string and replace all instances of hyperlinks into clickable html hyperlinks. I found an example in this thread: Easiest way to convert a URL to a hyperlink in a C# string? but was unable to reproduce it in python :(

  • Clarification needed about Python CSV file format parsing

    - by HH
    Format is like: CHINA;2002-06-25 00:00:00.000;5,60 CHINA;2002-06-26 00:00:00.000;5,32 CHINA;2002-06-27 00:00:00.000;5,31 and I try to use Python's CSV tools to parse it but cannot understand the paragraph, source: And while the module doesn’t directly support parsing strings, it can easily be done: import csv for row in csv.reader(['one,two,three']): print row Could someone clarify the line ['one,two,three']? How would you use it with format A;B;C?

  • python how to find the median of a list

    - by user3450574
    I'm trying to write a function named median that takes a list as an input and returns the median value of the list. I'm working with Python 2.7.2 The list can be of any size and the numbers are not guaranteed to be in any particular order. If the list contains an even number of elements, the function should return the average of the middle two. This is the code I'm starting with: def median(list): print(median([7,12,3,1,6,9]))

  • python: equivalent to Javascript "||" to override non-truthful value

    - by Jason S
    In Javascript I can do this: function A(x) { return x || 3; } This returns 3 if x is a "non-truthful" value like 0, null, false, and it returns x otherwise. This is useful for empty arguments, e.g. I can do A() and it will evaluate as 3. Does Python have an equivalent? I guess I could make one out of the ternary operator a if b else c but was wondering what people use for this.

  • Python: if key in dict vs. try/except

    - by LeeMobile
    I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case: I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on. Which way is better? try: A["blah"] = B["blah"] except KeyError: pass or if "blah" in B: A["blah"] = B["blah"] "Do and ask for forgiveness" vs. "simplicity and explicitness". Which is better and why?

  • How do I set a property in python using its string name

    - by dave
    Hey, here's a dumb question: how can I set an object property given its name in a string. I have a dictionary being passed to me and I wish to transfer its values into namesake properties using code like this: for entry in src_dict: if entry.startswith('can_'): tgt_obj[entry] = src_dict_profile[entry] I'm still a bit of a noob with Python so would appreciate some help. - dave.

  • C++ Vector vs Array (Time)

    - by vsha041
    I have got here two programs with me, both are doing exactly the same task. They are just setting an boolean array / vector to the value true. The program using vector takes 27 seconds to run whereas the program involving array with 5 times greater size takes less than 1 s. I would like to know the exact reason as to why there is such a major difference ? Are vectors really that inefficient ? Program using vectors #include <iostream> #include <vector> #include <ctime> using namespace std; int main(){ const int size = 2000; time_t start, end; time(&start); vector<bool> v(size); for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - 27 seconds Program using Array #include <iostream> #include <ctime> using namespace std; int main(){ const int size = 10000; // 5 times more size time_t start, end; time(&start); bool v[size]; for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - < 1 seconds Platform - Visual Studio 2008 OS - Windows Vista 32 bit SP 1 Processor Intel(R) Pentium(R) Dual CPU T2370 @ 1.73GHz Memory (RAM) 1.00 GB Thanks Amare

  • 2d convolution using python and numpy

    - by mikip
    Hi I am trying to perform a 2d convolution in python using numpy I have a 2d array as follows with kernel H_r for the rows and H_c for the columns data = np.zeros((nr, nc), dtype=np.float32) #fill array with some data here then convolve for r in range(nr): data[r,:] = np.convolve(data[r,:], H_r, 'same') for c in range(nc): data[:,c] = np.convolve(data[:,c], H_c, 'same') It does not produce the output that I was expecting, does this code look OK Thanks

  • Best (or appropriate) WSGI server for this Python script? - Python

    - by RadiantHex
    Hi folks, I'm having quite a problem deciding how to serve a few Python scripts. The problem is that the basic functionality could be generalized by this: do_something() time.sleep(3) do_something() I tried various WSGI servers, but they have all been giving me concurrency limitations, as in I have to specify how many threads to use and so on. I only wish that the resources on the server be used efficiently and liberally. Any ideas?
