At first glance, the Python modulo operator may not grab your attention. Yet, as you’ve seen, there’s so much to this humble operator. From checking for even numbers to encrypting text with ciphers, you’ve seen many different uses for the modulo operator.

**In this course, you’ve learned how to:**

- Use the
**modulo operator**with`int`

,`float`

,`math.fmod()`

,`divmod()`

, and`decimal.Decimal`

- Calculate the results of a
**modulo operation** - Solve
**real-world problems**using the modulo operator - Override
in your own classes to use them with the modulo operator`.__mod__()`

Here are additional resources about python expressions, floating point arithmetic, cryptography, and more:
