[FIXED] How do I take the average (mean) of inputted numbers in Python?

Issue

I would like to take create a code that takes an input of numbers, and then takes the average (mean) of these numbers. So far, I have this:

from statistics import mean

numbers=int(input("Enter some numbers. Seperate each number by a space: ") 
average=mean(grades)
print(average)

Running this code gives me an error stating "invalid literal for int() with base 10: ' 12 13 14 15 16 17 17'". I have tried to convert the input into a list, but this also failed; I don't know what else to do or try.

Solution

numbers=[int(x) for x in input("Enter some numbers. Seperate each 
number by a space: ").split()]
print(numbers)
average=mean(numbers)
print(average)
