What’s inside Python ‘for’ loop?

Python is already so slow that it's comparable to normal iteration. But here's an example:

  timeit('next(x)', 'x = iter(range(1<<30))', number=1<<22)  # 0.22

  timeit('''try: raise StopIteration()
  except StopIteration: pass''', number=1<<22)  # 0.78

I pray for the day that Tensorflow has an official rust (or scala) api.
