Finding dead code

[wavic]

Try https://pypi.python.org/pypi/vulture

There are some Python IDE's which will mark unused variables or code which is not used. Sublime Text will do it, I think. May be Atom too.

Edit:
I've wrote this simple code:

#!/usr/bin/env python3
import sys

a = 2
b = 3
c = 4


def print_hw():
    print("hello, world")


def add_nums(x, y):
    return x + y


def main():
    print(add_nums(a, b))
    print(dir(__name__))

if __name__ == '__main__':
    sys.exit(main())

So, Sublime, Atom and Ninja IDE, no one of these has showed the unused code...

I've tried pychecker, pyflakes and vulture. Only the last one has printed out some result.

victor@jerry:~$ vulture -v dead_code_test.py | grep 'Unused'
dead_code_test.py:6: Unused variable 'c'
dead_code_test.py:9: Unused function 'print_hw'
