I'm trying to format a file so that it can be inserted into a database, the file is originally compressed and arround 1.3MB big. Each line looks something like this: 398,%7EAnoniem+001%7E,543,480,7525010,1775,0 This is how the code looks like that parses this file: Village = gzip.open(Root+'\\data'+'\\' +str(Newest_Date[0])+'\\...
I was writing a script to inspect python's version on my system and I've noticed that python -V writes to the error stream, while python -h, for instance, uses the standard output. Is there a good reason for this behavior? ...
Hey there, was wondering if anyone could help a newbie on SQL and Python. I thought I had a pretty decent grasp of it, however something odd happened recently. Here is the the following code snipped from a larger portion: try: self.db.query("SELECT * FROM account WHERE email = '{0}' AND pass = '{1}'".format(self.mail.strip(self...

I'm playing around with list comprehensions and I came across this little snippet on another site: return ''.join([`num` for num in xrange(loop_count)]) I spent a few minutes trying to replicate the function (by typing) before realising the num bit was breaking it. What does enclosing a statement in those characters do? From what I c...

Simplified examples of my data as input by users: one, two, three, four, five one. two. three, four. five. "I start with one, then do two, ma...
Not really too sure how to word this question, therefore if you don't particularly understand it then I can try again. I have a file called example.txt and I'd like to import this into my Python program. Here I will do some calculations with what it contains and other things that are irrelevant. Instead of me importing this file, goin...
Using Python module re, how to get the equivalent of the "\w" (which matches alphanumeric chars) WITHOUT matching the numeric characters (those which can be matched by "[0-9]")?

I want to get the list of running processes on the Mac, similar to what you get from 'ps -ea' I have tried os.popen('ps -ea') but this only lists a small subset of the processes, presumably those owned by the owning shell. Other options I have tried are 'sh -c /bin/ps -ea' 'bash -c /bin/ps -ea' 'csh -c /bin/ps -ea' Running as root vi...
I have a program which takes a long time to complete. I would like it to be able to catch SIGINT (ctrl-c) and call the self.save_work() method. As it stands, my signal_hander() does not work since self is not defined by the time the program reaches signal_handler(). How can I set it up so self.save_work gets called after a SIGINT? #...

I have 2 dimensional list created at runtime (the number of entries in either dimension is unknown). For example: long_list = [ [2, 3, 6], [3, 7, 9] ] I want to iterate through it by getting the ith entry from each list inside the long_list: for entry in long_list.iter(): #entry will be [2, 3] then [3, 7] then [6, 9] I know tha...

Hi, I have a python (well, it's php now but we're rewriting) function that takes some parameters (A and B) and compute some results (finds best path from A to B in a graph, graph is read-only), in typical scenario one call takes 0.1s to 0.9s to complete. This function is accessed by users as a simple REST web-service (GET bestpath.php?f...

Coming from a java background I'm used to having a bunch of properties files I can swap round at runtime dependent on what server I'm running on e.g. dev/production. Is there a method in python to do similar, specifically on Google's App Engine framework? At the minute I have them defined in .py files, obviously I'd like a better separ...
