I don't understand why my recursive function hits the recursion limit
inside the timeit.Timer when it works outside of it.
Is there any way to see the current recursion depth at a particular
moment?
import inspect
def rec(count=100):
if not count:
return
print len(inspect.getouterframes(inspect.currentframe()))
rec(count-1)
rec()
