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

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"

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

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?

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
