Re: Query Regarding IDE for python for GUI Apps

Hi,

I swear by PyDev (http://pydev.org/), which is a plugin for Eclipse
that gives you a full blown IDE for Python. For large projects, I
think this is the way to go. For casual editing of python files, I
still use Emacs or Vim.

The feature list is quite impressive. Among other things it features
IntelliSense, so you can navigate to the source of a method by simply
Ctrl-clicking it. It also has support for refactoring, so it is for
example possible to change the name of a method by just right clicking
it, select "change name" and choose a new name. Then all calls in the
project to this method will be updated to use the new name.

Having a syntax check, warning for unknown identifiers and the wrong
number of arguments to functions directly in the IDE, saves a lot of
time, since I for example don't have to run the code to see that I
misstyped the name of a method. Pylint (http://www.logilab.org/857) is
also optionally integrated directly into the IDE and that gives me
increased code quality.

I have tried lots of IDE's for Python, but PyDev is the one I go back
to for large projects. Try it and see if you like it.
