Hi,
How can i print only certain words from a string in python ?
lets say i want to print only the 3rd word (which is a number) and the 10th one
while the text length may be different each time
mystring = "You have 15 new messages and the size is 32000"
thanks.
This is a question I have wondered about for quite some time, yet I have never found a suitable solution. If I run a script and I come across, let's say an IndexError, python prints the line, location and quick description of the error and exits. Is it possible to automatically start pdb when an error is encountered? I am not against having an extra import statement at the top of the file, nor a few extra lines of code.
Is there any short way to achieve what APT does in Python ?
I mean, when the package manager prompts a yes/no question followed by "[Yes/no]".
The scripts accepts YES/Y/yes/y or "enter" (defaults to Yes as hinted by the capital)
The only thing I find in the official doc is input/raw_input..
I know it's not that hard to emulate, but it's annoying to rewrite :|
I'm looking for a quick bash script or program that will allow me to kick off a python script in a separate process. What's the best way to do this? I know this is incredibly simple, just curious if there's a preferred way to do it.
How can I log into my Launchpad account in a python script? Any sample code would be appreciated.
The login url is https://launchpad.net/+login and then redirect to something like https://login.launchpad.net/fJLVSRbxPfKTpVDr/+decide
Thanks in advance!
I am looking for a component that resizes and ftp's images to a website.
It doesn't have to be free.
In fact, I prefer something we pay for that comes with solid support.
It has to be able to transfer multiple images at once too.
How can I split a line in Python at a non-printing ascii character (such as the long minus sign hex 0x97 , Octal 227)?
I won't need the character itself. The information after it will be saved as a variable.
Well i'm learning Python cuz' i think is an awesome and powerful language like C++, perl or C# but is really really easy at same time. I'm using JetBrains' Pycharm and when i define a function it ask me to add a "Documentation String Stub" when i click yes it adds somethin like this:
"""
"""
so the full code of the function is something like this:
def otherFunction(h, w):
"""
"""
hello = h
world = w
full_word = h + ' ' + w
return full_word
I would like to know what these (""" """) symbols means, Thanks.
Ps.Data: Sorry for my bad english :D
In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example:
mydict = {'a': [3,5,6,43,3,6,3,],
'b': [87,65,3,45,7,8],
'c': [34,57,8,9,9,2],}
for k in mydict.iterkeys():
print k
gives me:
a
c
b
How can I do something similar in Javascript?
I am trying really hard to make a sliding frame containing widgets in tkinter in python. There is this frame inside a big window with different widgets. And as soon as i click on the next button on that frame the frame should slowly slide towards the left and vanish ultimately. As soon as it vanishes, i want new frame with widgets to come sliding towards right.
What should i do?
Anticipating your suggestions and ideas.
I'm curious if their is some python magic I may not know to accomplish a bit of frivolity
given the line:
csvData.append(','.join([line.split(":").strip() for x in L]))
I'm attempting to split a line on :, trim whitespace around it, and join on ,
problem is, since the array is returned from line.split(":"), the
for x in L #<== L doesn't exist!
causes issues since I have no name for the array returned by line.split(":")
So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot?
Cheers!

What's the best way to sanitise user input for a Python-based web application? Is there a single function to remove HTML characters and any other necessary characters combinations to ensure that an XSS or SQL injection attack isn't possible?
I'm building a few small prototypes in Silverlight and have quite a bit of .NET experience, but Ive never had the need to contact the server from Silverlight.
Im really just after a really quick solution for the purposes of prototyping and I'll be needing to call the server and do a few things, like server a generated image from the server, receive basic responses from the server, but nothing too fancy.
Is .NET RIA Services the best way to do this or is it overkill?
The documentation for RIA Services is huge, 1 hour long video introductions, 26-part series blogs, etc... seems like its overkill.
Is there a quick REST based project I could create, or should RIA services be the way to go?
What is the shortest / most elegant way to implement the following Scala code with an abstract attribute in Python?
abstract class Controller {
val path: String
}
A subclass of Controller is enforced to define "path" by the Scala compiler. A subclass would look like this:
class MyController extends Controller {
override val path = "/home"
}
Im using python to access a MySQL database and im getting a unknown column in field due to quotes not being around the variable.

How do i manually insert double or single quotes around the value of s?
I've trying using str() and manually concatenating quotes around s but it still doesn't work.
The sql statement works fine iv double and triple check my sql query.
Does anybody know any module in Python that computes the best bipartite matching?
I have tried the following two:
munkres
hungarian
However, in my case, I have to deal with non-complete graph (i.e., there might not be an edge between two nodes), and therefore, there might not be a match if the node has no edge. The above two packages seem not to be able to deal with this.
Any advice?
In python if a string contains the following,
print valid_str
The output of this is
Record is positive in tone:
It emphasizes "what a child can do and his or her achievements, as opposed to what he or she cannot do," explains the It is useful for progress and achievements during office conferences
How to search for the pattern It is useful in the above string and if not found return something.
Thanks..
I want to break a Python string into its characters.
sequenceOfAlphabets = list( string.uppercase )
works.
However, why does not
sequenceOfAlphabets = re.split( '.', string.uppercase )
work?
All I get are empty, albeit expected count of elements
I'm running OS X Leopard. I followed this site to install it. Trying to run any demo script, I now get "No module named opencv.cv", which is obviously stopping me from doing any programming. I am running python 2.5.1 (yes, I know it's kind of old).
Why would this be, and how can I solve it?
Thanks
I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_...
I was wondering if there's a way to go through all of these functions in some main function that calls for them.
something like:
foreach function_that_has_site_ as coolfunc
if coolfunc(blabla,yada) == true:
return coolfunc(blabla,yada)
so it would go through them all until it gets something that's true.
thanks!
