Description

The following problems are specified in the file homework_5_skel.py. Complete the problems in that file and rename it homework_5.py before uploading it to Moodle. 

Remember len(s) returns the length of a string s, and that s[i] returns the ith character of s. 

Some of these problems must use while instead of for. Make sure their termination is guaranteed.

A counter 

Define a function counter0 which takes no inputs and has the following effect when run: It repeatedly queries the user, asking for either a numerical input, or the letter ’q’ (to quit). The user types in a sequence of numbers and finally the letter ’q’. The program then returns 

• how many numbers entered 

• the sum of the numbers entered 

• the maximal number entered 

• the average of the numbers entered
