TypeError: not all arguments converted during string formatting

[RedSkeleton007]

Why is a basic print statement asking for string formatting?:

#!/usr/bin/env python3
#PracticePythonExercise02.py

number = input("Enter a number: ")

if number % 2 == 0:
    print("the number is even.")
else:
    print("the number is odd.")

Error:
>>> ================================ RESTART ================================
>>> 
Enter a number: 4
