This line is the problem.  When you write 
    foo.bar
in the source code 'foo' is the name of an object and 'bar' is the
name of its member.  As you have it here you are printing each object
of the getopt module by a *reference* to it ('i'), then trying to get
the member of the getopt module *named* i, which probably doesn't
exist.

Instead try this

    print i , i.__doc__
