class foobar(object):
def func(arg):
print 'foobar.func: %r' % arg
def caller(a):
__f.func()
>>> main: ['foo']
>>> caller: 'foo'
>>> foobar.func: <__main__.foobar object at 0x00A45550>
class foobar(object):
def func(self, arg):
print 'foobar.func: %r' % arg
def caller(a):
__f.func(a)
>>> main: ['foo']
>>> caller: 'foo'
>>> foobar.func: 'foo'
You're already passing the object as an argument in the first case.
