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.
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.
Hi,
I'm currently doing a project that requires some fast TSP solving (about 50-100 nodes in 2 seconds). There are a lots of approximation algorithms out there, but I don't have time nor will to analyze them and code them myself.
Are there any free libraries that can solve TSP problem (approximation will do too)? Something like sortedNodes = solveTspPrettyPlease(nodes, 2sec) would be just great.
Thanks in advance.
What is the proper indentation for Python multiline strings within a function?
def method:
string = """line one
line two
line three"""
or
def method:
string = """line one
line two
line three"""
or something else?
It looks kind of weird to have the string hanging outside the function in the first example.
Thanks.
Which technology is better to use in terms of performance for high performance scalable web application? PHP or Python?
The project is going to involve database.
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?
Hello,
I'm trying to start an application using Python. I've seen that some people use startfile but I also read that it only works with Windows. I'm using Mac systems and hoping for it to work with them.
Thanks,

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 need a way to determine the space remaining on a disk volume using python on linux, Windows and OS X. I'm currently parsing the output of the various system calls (df, dir) to accomplish this - is there a better way?
I need to change some characters that are not ASCII to '_'.
For example,
Tannh‰user - Tann_huser
If I use regular expression with Python, how can I do this?
Is there better way to do this not using RE?
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 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!
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
Hi, I have an application that starts several threads using
gobject.timeout_add(delay, function)
Now in my function I want to test and set on some variable, e.g.
def function(self):
if flag == True:
flag = False
doSomething()
Now to make this threadsafe, I would have to lock the function using some mutex lock.
Is this possible with Gtk? Or can I use the Python Lock objects from threading?
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.

What is the pythonic way to test if there is a tuple starting with another tuple in collection? actually, I am really after the index of match, but I can probably figure out from test example
for example:
c = ((0,1),(2,3))
# (0,) should match first element, (3,)should match no element
I should add my python is 2.4 and/or 2.5
thanks
Hi all
I am a newbie to the python. Can I unhash, or rather how can I unhash a value. I am using std hash() function. What I would like to do is to first hash a value send it somewhere and then unhash it as such:
#process X
hashedVal = hash(someVal)
#send n receive in process Y
someVal = unhash(hashedVal)
#for example print it
print someVal
Thx in advance
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
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.

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.
I'm new in python and I'm having some issues doing a simple thing.
I've an array (or list as it's said in pyton) like this:
list = [ 'NICE dog' , 'blue FLOWER' , 'GOOD cat' , 'YELLOW caw']
As you see each element of this array contains some words. These words is both lowercase and uppercase.
How I can delete from this array each lowercase words?
For example I'd like to have as result this list:
list = [ 'NICE' , 'FLOWER' , 'GOOD' , 'YELLOW']
