vim and python scripts debugging

Try pyclewn. It allows to use vim as front end for pdb. You can create/delete break points, control flow of debugging process, look at values of your variables. All from vim!

Also try https://pypi.python.org/pypi/pudb - its like pdb but more advanced. Contains code highlighting, stack, showing avaliable values, etc. Not only-vim solution but for me works perfectly.

Three Steps:

Install:

pip install pudb

Paste set_trace in code

from pudb import set_trace; set_trace()

Run your code

Use pdb:

import pdb
def main():
  list = [1,2,3]
  pdb.set_trace()
  list = [2,3,4]

if __name__ == '__main__':
    main()

Now run using :!python % and you'll hit your breakpoint and be able to debug interactively like in gdb.
