Get the name of a function

[gervaz]

Hi all, is there a way to retrive the function name like with
self.__class__.__name__?

Using self.__dict__.__name__ I've got
.... print(self.__dict__.__name__)
....<function test at 0x0178DDF8>

But I really just want the function name, so 'test'

Any help?

Thanks,

Mattia

yes, but not reliably:

Python 2.6.4rc2 (r264rc2:75497, Oct 20 2009, 02:55:11)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Er, where did `self` magically come from?

<function test at 0x0178DDF8>

Courtesy of the "Observations on the three pillars of Python execution" thread:

from inspect import currentframe

def foobar():
my_name = currentframe().f_code.co_name
print(my_name)

I would recommend against a function knowing its own name though,
unless it's for debugging or necessary metaprogramming purposes.

Cheers,

Not really. There may not be any such thing as "the function name". A
function may have zero names, it may have a dozen names. It may have
names but only in namespaces that aren't accessible.

This question comes up at least once a month, so look back through the
group for threads about finding an object's name, finding a
parameter's name, etc.

Here's a nice article on introspection, but what it talks about as a
"function name" probably isn't what you're interested in:
