How to see python default methods from inside

[mariolucas75]

Dear forum,

Could you please advise how / where to see from what script Python standard built-in functions or methods are composed of ?
For example - a Python method split()... what is the script for this split itself?
From what lines method "split()" is composed of ?

Or in general any other standard built-in method scripts?

Thks

So much
