use python to solve this problem

Problem 3- contains.py: Sub-list containment You will write a function to determine whether a given sub-list" s appears within another given list 1. The problem will guide you through the problem breakdown. Essentially, first you can solve the easier problem if the "sub-list" s appears within 1 at a specific position i. Then Practice goal: Guided practice with modular thinking and programming. Problem 3a Partial equality [5 points] Write a function contains_at that accepts two lists, 1 and s, and an integer i and returns True if and only if the sub-list of 1 starting a index i and ending at index ilen (s)-1 is equal to s. The lists should not be modified in any way. Practice goal: List slices and list equality (the implementation could be a one-liner). Problem 3b - Sub-list [10 points] Write a function contains that accepts two lists, 1 and s, and returns True if and only if 1 contains s at any valid position (i.e, any position 0i
