Python code for the following function.

Create all the functions and do not use python functions like numpy, use variables, loops, if statements and own functions. You can use only functions from math and copy. Explain with comments each line of the code. This code should be looking as for beginner python users, so do not be so sophisticated or give a well-explained comment otherwise.

Write a function def GaussElim(Aaug):

Aaug: an augmented coefficient matrix of size N x N+1, containing the equation set: Ax=b return value x-a vector (array) of size N, containing the solution to Ax = b (do not use partial pivoting)

To test the function write and call a def main() that creates an augmented matric, calls GaussElim, and print the solution. Use the matric below to demonstrate that your function gets the correct answer.
