[Tutor] How can a function know where it was called from

[Ewald Ertl]

Hi Ben!

After looking at the modules I detected the traceback-Module in my installation:

>>> import traceback
>>> def two():
...     one()
...
>>> two()
>>> def one():
...     print traceback.extract_stack()
...
>>> def two():
...     one()
...
>>> two()
[('<stdin>', 1, '?', None), ('<stdin>', 2, 'two', None), ('<stdin>', 2, 'one', None)]

maybe this could be a start for your investigation
