Is There a Python Equivalent to the Sum() Function for Multiplication?

The Elusive Product Function - A Pythonic Alternative

While Python's sum() function conveniently provides the sum of numbers in an iterable, there seems to be a noticeable lack of an analogous function for multiplication. Understandably, developers often seek a function that performs a similar operation but for multiplying values, similar to sum().

However, despite its intuitive appeal, such a built-in function, such as product(), does not exist in Python's standard library. Historically, creator Guido van Rossum vetoed the idea due to potential confusion with the multiplication operator (*).

Despite the absence of a dedicated product() function, there are alternative approaches to achieve multiplication accumulation. One solution is to use the reduce() function in conjunction with the operator module. Here's an example:

from functools import reduce
import operator

product = reduce(operator.mul, (3, 4, 5), 1)  # Initialize with 1 for multiplication accumulation
# Result: 60
Copy after login

In this example, reduce() applies operator.mul to the elements of the sequence (3, 4, 5) and accumulates the results into the variable product. Note that we initialize product with 1 to avoid starting with 0, which would incorrectly multiply all elements to 0.
