Ok, but how can I retrieve information about built-in functions (if any)?
>>> inspect.getsourcefile(itertools.product)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python31\lib\inspect.py", line 439, in getsourcefile
filename = getfile(object)
File "C:\Python31\lib\inspect.py", line 406, in getfile
raise TypeError('arg is a built-in class')
TypeError: arg is a built-in class
