Question

Write a program which reads integers from 1-100 and counts the occurances of each, an example: 8,4,4,2,1,3,7,7,0 and the results should be like: 8 occurs once 4 occurs twice 2 occurs once 1 occurs once 3 occurs once 7 occurs twice 0 occurs once
This program must be made in Python. Write a program which reads integers from 1-100 and counts the occurances of each, an example: 8,4,4,2,1,3,7,7,0 and the results should be like: 8 occurs once 4 occurs twice 2 occurs once 1 occurs once 3 occurs once 7 occurs twice 0 occurs once
