Answer 1

Musharaf Nazir ,

what issue do you have in understanding:

> the mathematical part of a polynomial? in this case you can use wikipedia to find more details.

> the coding itself? there are 2 functions that are doing the same but in different ways.
the first way is using a regular named function.
the second way is using a lambda function, which is an anonymous function.
both functions are explained in the related python tutorials.
