I keep hearing that Dive Into Python 3 is more pythonic than Dive Into Python. I have some experience in programming, but at the same time I'm new to Python (only went thru the official tutorial so far). I will be using Python 2.x at work. Would it make sense to use Dive Into Python 3 to learn Python 2.x? ...
Python beginner here, so I apologize if this question has a simple answer. (I hope it does.) I am working on a python module--a plugin for a larger program. I'm trying to develop the module using the Eclipse IDE (with pydev), which means I need to be able to run this module stand-alone, i.e. not as a plugin from the larger program. ...
Why can I not change global variables from inside a function, using exec()? It works fine when the assignment statement is outside of exec(). Here is an example of my problem: >>> myvar = 'test' >>> def myfunc(): ... global myvar ... exec('myvar = "changed!"') ... print(myvar) ... >>> myfunc() test >>> print(myvar) test ...

Hi all, I have a loop starting with for i in range(0, 100), and inside the loop, normally it would run correctly, but sometimes due to network conditions it would fail. Currently i have it set so that when failed, it would continue in except clause (continue on to the next number for i). I was wondering whether it is possible for me to...
a = 0 if a == False: print a in php I can say: $a = 0; if $a === false { echo $a; } The triple === in php check for the value within the same type, thus making the integer 0 not be read as a boolean value False How can I do this in python? I would like to differentiate between 0 the integer and False the boolean value in a si...
Recently I've found myself testing an aplication in Froglogic's Squish, using Python to create test scripts. Just the other day, the question of how much memory the program is using has come up, and I've found myself unable to answer it. It seems reasonable to assume that there's a way to query the os (windows 7) API for the information,...

Is there any alternate way to simulate the timeout? All I want to do is allow the code to talk the remote server for a fixed amount of time. Perhaps any alternative built-in library...
