python- Trouble Converting User Input to Integer Format

Question

user_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)

I am simply trying to obtain input from the user and do certain tests on it. For example, if number > 0:. In order to do this, I assumed that user input data is automatically stored as a string and to remedy this, one would do what is provided in the code box. However, when doing this operation, I get ValueError: invalid literal for int() with base 10: 'Enter a number and I will tell you the sum of the multiples of 3 and 5 leading up to it.' Clearly I am doing this wrong. Can someone shed light on how to do this correctly?

-Thank you in advance :)

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)
