Python tutorial | Itertools, Permutations and Combinations | Competitive Programming | coding basics

Python provides direct methods to find permutations and combinations of a sequence. These methods are present in itertools package.

First import itertools package to implement the permutations method in python. This method takes a list as an input and returns an object list of tuples that contain all permutations in a list form.

Combination, this method takes a list and an input r as an input and return an object list of tuples which contain all possible combination of length r in a list form.

Python is an interpreted high-level general-purpose programming language.
Python is the most in-demand programming language used for AI(artificial intelligence).
Competitive programming is a mind sport usually held over the Internet or a local network, involving participants trying to program according to provided specifications.

Hi good sir! I'm really hoping you could help me out.
I'm doing some project and I could really use your help.
here's what I have to do.
1. import an excel file in python. [this contains combination of 7 numbers, one number each cell]
2. filter out those combinations. [by filter, I mean that if the combination contains a certain number in a criteria, it will be removed, example is: if it contains more than 2 in the set EVEN_No=2, 4, 6, 8, 10, 12, 14, 16, 18, 20, then than combination will be removed]
3. export the remaining combinations in excel or csv file.
I will be really grateful sir!
