I have two for loops, both alike in dignity. I'd like to have a counter incremented during each inner iteration. For example, consider this template: from jinja2 import Template print Template(""" {% set count = 0 -%} {% for i in 'a', 'b', 'c' -%} {% for j in 'x', 'y', 'z' -%} i={{i}}, j={{j}}, count={{count}} {% set count =...

I'm new to Python, with a background in statically typed languages including lots and lots of Java. I decided on PyDev in eclipse as an IDE after checking features/popularity etc. I was stunned that auto-complete doesn't seem to work properly for builtins. For example if I try automcomplete on datafile after: datafile = open(directory...

I am running a Python GUI application. I want to invoke and control GDB from it, like load an executable file, set breakpoints etc. I see that GDB has a command line interface which can be used by sending strings to the GDB process, but I want to do it the Python way. Is there a gdb.py? I see that "archer" branch has something like "impo...
I'm trying to implement a simple method to read new lines from a log file each time the method is called. I've looked at the various suggestions both on stackoverflow (e.g. here) and elsewhere for simulating "tail" functionality; most involve using readline() to read in new lines as they're appended to the file. It should be simple enou...

Hey everyone. I just made a small app and then wrote a setup.py file for it. Everything seems to be working, except I can't figure out a small thing. When passing the bdist option to setup.py, it creates the archive gzipped tar file. When I open that file, I notice that the directory structure is: > usr > lib > python2.6 >...

The addition of collections.defaultdict in Python 2.5 greatly reduced the need for dict's setdefault method. This question is for our collective education: What is setdefault still useful for, today in Python 2.6/2.7? What popular use cases of setdefault were superseded with collections.defaultdict? ...

I'm working on a GUI program in which I already bind a start button with one event, and when I click the start button, the event runs as I like. My question is, if I want my program to start the event immediately after the GUI program starts, which means the start button is immediately being "clicked" once the program starts, how do I do...

The relevant part is class Plugin(object): class __metaclass__(type): def __init__(cls, name, bases, dict): type.__init__(name, bases, dict) registry.append((name, cls)) ...
