Modulo reveals whether division by two leaves a remainder.
What is Even or Odd?
Modulo reveals whether division by two leaves a remainder.
Determine whether an integer is even or odd.
When should you use it?
- Learn Python syntax through a practical example.
- Build a foundation for larger programming problems.
- Test an idea quickly without a local setup.
Example code
main.py
number = 42
# Even numbers leave no remainder when divided by 2.
kind = "even" if number % 2 == 0 else "odd"
print(f"{number} is {kind}")Expected output
42 is evenHow it works
A remainder of zero means the number is divisible by two.
Change the values and run the program in the CodeUtility online Python compiler without installing Python locally.
