Answer 1

You are not actually prompting for a number. The user_input in your example is the string literal Enter a number and I will tell you the sum of the multiples of 3 and 5 leading up to it., which can not be converted to a number.

User input can be prompted with input().

user_input = input("Enter a number and I will tell you the sum of the multiples of 3 and 5 leading up to it.")
number = int(user_input)
