divmod - Python

Introduction

In Python, divmod() is a built-in function that takes two numbers as arguments and returns the tuple (a, b) containing the quotient and remainder when the first argument is divided by the second. In other words, the result of the expression divmod(a, b) is (a // b, a % b).

Syntax

divmod(a, b)

Parameters

• a: the numerator
• b: the denominator

Return Value

The return value of divmod() is a tuple (a // b, a % b), where a // b is the quotient and a % b is the remainder.

Example

>>> divmod(10, 3)
(3, 1)
>>> divmod(7, 2)
(3, 1)
>>> divmod(18, 4)
(4, 2)

Use Cases

• The divmod() function can be used to perform integer division and obtain the remainder in a single step.
• It can be used to compute the partial quotient and remainder when dividing a large number by a small number, which can be useful in certain algorithms.
• The divmod() function can also be used to implement a custom __divmod__() method for a class, allowing instances of the class to be used with the built-in divmod() function.

Conclusion

In conclusion, divmod() is a useful and versatile function in Python that can simplify certain arithmetic operations and implementation details.
