Partial functions in Python offer a convenient way to create new functions from existing ones by fixing certain arguments. They provide flexibility and readability, allowing for cleaner code and improved maintainability.

In this article, we’ll explore partial functions in Python, understand how they work, and demonstrate their practical applications with up-to-date examples.

Understanding Partial Functions

Partial functions are functions that are created by fixing a certain number of arguments of an existing function. They are defined in the functools module and can be used to "freeze" some portion of a function's arguments, resulting in a new function with reduced arity (number of arguments).

This concept is particularly useful when you need to create specialized functions from generic ones without repeating code. Let's delve into an example to illustrate this:

from functools import partial

# Original function
def power(base, exponent):
    return base ** exponent

# Creating a partial function with fixed base
square = partial(power, exponent=2)

# Using the partial function…
