Write a Python program to do the following: 1. Implement the following function: MV is a list of integers that are >= 0. Return the minimum value in MV that is > 0. If all values in MV are 0, return -1. def cal_min(MV): 2. Read a list of integer values from an input file named "integers.txt", and take every other number to create a list MV. By calling cal_min(MV), get the minimum value as described in Q1 and print MV and the return value. For example, from the following input file: 2, 3, 0, 5, 7,4 MV consists of [2, 0, 7]. And cal_min(MV) will return 2
