[SOLVED] Determine function name from within that function (without using traceback)

Issue

In Python, without using the traceback module, is there a way to determine a function’s name from within that function?

Say I have a module foo with a function bar. When executing foo.bar(), is there a way for bar to know bar‘s name? Or better yet, foo.bar‘s name?

#foo.py  
def bar():
    print "my name is", __myname__ # <== how do I calculate this at runtime?

Solution

Python doesn’t have a feature to access the function or its name within the function itself. It has been proposed but rejected. If you don’t want to play with the stack yourself, you should either use "bar" or bar.__name__ depending on context.

The given rejection notice is:

This PEP is rejected. It is not clear how it should be implemented or what the precise semantics should be in edge cases, and there aren’t enough important use cases given. response has been lukewarm at best.
