Python supports a wide range ofarithmetic operators that you can use when working withnumbers in your code. One of these operators is themodulo operator (%), which returns the remainder of dividing two numbers. Modular operations are useful to check if a number is even or odd, simplifying cycling through data, and doing non-decimal based units conversion.

In this course, you’ll learn:

• Howmodulo works in mathematics
• How to use the Python modulo operator with differentnumeric types
• How Python calculates the results of amodulo operation
• How to override.__mod__() in your classes to use them with the modulo operator
• How to use the Python modulo operator to solvereal-world problems

The code in this course was tested with Python 3.9.0,% has not change much and older versions should be compatible.
