Non integer of type?

Question

Trying to find the average of a group of numbers. Googled solutions (which looks nice) but get the following error message:

Traceback (most recent call last):
File "..\Playground\", line 4, in <module>
print('Percent of X: '+str(X*Z)+'%')
TypeError: can't multiply sequence by non-int of type

What do they mean by "non integer of type"?

X = input()
Y = input()
Z = 100/(int(X)+int(Y))
print('Percent of X: '+str(X*Z)+'%')
print('Percent of Y: '+str(Y*Z)+'%')

Answer 1

input() always returns a string. You need to convert these to floats (or integers) to do mathematical operations.

X = float(input())
Y = float(input())
Z = 100/(int(X)+int(Y))
print('Percent of X: '+str(X*Z)+'%')
print('Percent of Y: '+str(Y*Z)+'%')
