How to get the function name as string in Python?

I have a function named func, I'd like to be able to get the functions name as a string.

pseudo-python :

def func () :
    pass

print name(func)

This would print 'func'.

That's simple.

print func.__name__

EDIT: But you must be careful:

>>> def func():
...     pass
... 
>>> new_func = func
>>> print func.__name__
func
>>> print new_func.__name__
func

Use __name__.

Example:

def foobar():
    pass

bar = foobar

print foobar.__name__   # prints foobar
print bar.__name__   # still prints foobar

For an overview about introspection with python have a look at http://docs.python.org/library/inspect.html

A couple more ways to do it:

>>> def foo(arg):
...     return arg[::-1]
>>> f = foo
>>> f.__name__
'foo'
>>> f.func_name
'foo'
>>> f.func_code.co_name
'foo'
