Note that a function's code object usually has the same name as the associated function, but not always,
since functions can be created dynamically.
Unfortunately, Python doesn't track the function objects on the stack (I've sometimes fantasized about submitting a patch for this).
Still, this is certainly "good enough" in most cases.

If this becomes an issue, you could extract the "real" function name from the source code—Python does track the 
filename and line number—or ask the garbage collector find out which function object refers to the code object. 
There could be more than one function sharing the code object, but any of their names might be good enough.

This is awesome. I ended up adding
os.path.basename(frame.f_code.co_filename) to this trace function to print the file containing the function called. –
