what is hash function mam?

It is a built-in function.

It is used to quickly compare dictionary keys while looking at a dictionary.

A hash function is a function from some sort of input to a number. In particular, a hash function takes arbitrarily sized inputs to a fixed size output. It â€śshrinksâ€ť the input space to a predefined output range.

There are two main uses for hash functions: data structures and security.
