In this tutorial, you'll learn about the Python modulo operator (%). You'll look at the mathematical concepts behind the modulo operation and how the modulo operator is used with Python's numeric types. You'll also see ways to use the modulo operator in your own code.

Feb 17, 2025 · Modulo operator (%) in Python gives the remainder when one number is divided by another. Python allows both integers and floats as operands, unlike some other languages. It follows the Euclidean division rule, meaning the remainder …

Nov 8, 2016 · The modulo operator returns the remainder after a division. If the division is even (like in 4 % 2) then there is no remainder, the result is 0. The modulus of 2 over 2 is zero: So 2 % 2 produces 0, which is a false value, and thus the if statement doesn't match. On the other hand, the modulus of 3 over to is one:

Function fmod() in the math module returns a result whose sign matches the sign of the first argument instead, and so returns -1e-100 in this case. Which approach is more appropriate depends on the application.

Summary: in this tutorial, you’ll learn about the Python modulo operator (%) and how to use it effectively. Python uses the percent sign (%) as the modulo operator. The modulo operator always satisfies the following equation: In this equation: N is the numerator. D is the denominator.

In Python, a common way to calculate modulo is using the dedicated modulo operator %. Alternatively, if you want to know both the result of the division and the remainder, you can use the built-in divmod() function.

Mar 12, 2025 · In Python, the modulo operator follows a straightforward syntax: Let's look at some basic examples: When we divide 7 by 3, we get 2 with a remainder of 1. The modulo operator gives us that remainder. Similarly, 15 divided by 4 gives 3 with a remainder of 3, and 20 divided by 5 gives exactly 4 with no remainder.

May 27, 2022 · In this tutorial, you’ll learn how the modulo operator (%) works in Python. The Python modulo operator is one of the many arithmetic operators that are available in Python and one that you’ll encounter often. Because of this, understanding the details of how this operator works is an important skill for any Python developer.

You can write efficient and precise Python code by understanding the modulo operator's precedence and using parentheses to modify it. So, remember these rules when writing Python expressions to ensure your operations give the intended results.

Jan 31, 2025 · Learn how to use the Python modulo operator (%) for calculations, loops, and logic with practical examples for IT professionals and developers. The Python modulo operator is a crucial yet often overlooked component of Python programming.
