I tried to profile the speed of itertools vs for loop using python's `timeit` module.

https://gist.github.com/ChaiBapchya/252f3ba9340006659b830bac06c961ef#file-itertools_vs_for-py

The results were disappointing.

```

$ python3 itertools_vs_for.py

------------For loop timeit-------------

65.127538488

------------itertool timeit-------------

99.43747415499999

```

Note - timeit function runs it for default 1000000 times.
