Myself, I usually only use it to put a docstring for the package...

Use reload:

# Let's assume we have a little module bogus.py with only a line " x = 3 "

import bogus
print bogus.x   # prints 3

# Through an external editor, we change bogus.py so that it reads " x = 4 "

reload(bogus)
print bogus.x   # should be 4 now
