PLEASE HELP: why doesn't this program work? its probably pretty wrong, not sure whats going on

Question

ASSIGNMENT: Download the file numbers.txt attached to this assignment. The file contains mostly numbers, but every so often, there is a string. Write a program NumberAverage.py to average all the numbers, ignoring the values that are not numbers. Hint: use exception handling to determine whether the data on the current line is a number or not.

Example execution:

There are 80 numbers in the file and their average is 51.92.

fo = open("numbers.txt", 'r')
line = fo.read().rstrip('\n')
numLines = 0
sumNumbers = 0
for i in line:
numLines += 1
try:
sumNumbers += int(i)
except ValueError or TypeError:
sumNumbers += 0
line = fo.read().rstrip('\n')
average = sumNumbers / numLines
print("There were " + numLines + " numbers in the file and they had an average of " + average + ".")

when I run this, I get "can only concatenate str (not "int") to str"

Answer 1

you need to cast numLines and average to a string in the print function

Answer 2

When i do this, I get "There were 1706 numbers in the file and they had an average of 3.6658851113716295." I should be getting 80 numbers with an average of 50 something. i think its because of the stripping? do you know how to fix it?

Answer 3

yh when you loop through, it is looping through each whitespace and digit, instead of each number

try fo.read.split() instead of the rstrip line
