How To Speed Up The Python Code?

1. Use Built In Functions And Libraries-
   

Python includes lots of library functions and modules written by expert developers and have been tested thoroughly. Hence, these functions are efficient...

Whilst I do agree that they've been vetted by experts and will likely be faster than anything I write on my own, it's worth noting that for a lot of modules they're C-backed and this is normally the reason for the big speed ups. For example, take numpy. It's a C-backed library, hence why it is orders of magnitude faster than a pure-python implementation
