Profile this

By Filip Salomonsson; published on September 03, 2009. Tags: bugs profiling python

Consider a very small python program, test.py:

label = "foo"

And then consider profiling that program with the very nice cProfile module:

$ python -m cProfile test.py

Finally, consider the consequences:

Traceback (most recent call last):

    func = label(entry.code)
TypeError: 'str' object is not callable

(File paths shortened because mine are horribly long.)

Now consider stabbing your heart out with a fork. Though perhaps I should see if I can fix it instead, and submit a patch.
