Python - math.prod() method Last Updated : 23 Jan, 2020 Comments Improve Suggest changes 2 Likes Like Report Math module in Python contains a number of mathematical operations, which can be performed with ease using the module. math.prod() method in Python is used to calculate the product of all the elements present in the given iterable. Most of the built-in containers in Python like list, tuple are iterables. The iterable must contain numeric value else non-numeric types may be rejected. This method is new in Python version 3.8. Syntax: math.prod(iterable, *, start = 1) Parameters: iterable: an iterable containing numeric values start: an integer representing the start value. start is a named (keyword-only) parameter and its default value is 1. Returns: the calculated product of all elements present in the given iterable. Code #1: Use of math.prod() method Python3 # Python Program to explain math.prod() method # Importing math module import math # list arr = [1, 2, 3, 4, 5] # Calculate the product of # of all elements present # in the given list product = math.prod(arr) print(product) # tuple tup = (0.5, 0.6, 0.7) # Calculate the product # of all elements present # in the given tuple product = math.prod(tup) print(product) # range seq = range(1, 11) # Calculate the product # of all elements present # in the given range product = math.prod(seq) print(product) # As the start value is not specified # it will default to 1 Output: 120 0.21 3628800 Code #2: if start parameter is explicitly specified Python3 # Python Program to explain math.prod() method # Importing math module import math # By default start value is 1 # but can be explicitly provided # as a named (keyword-only) parameter # list arr = [1, 2, 3, 4, 5] # Calculate the product of # of all elements present # in the given list product = math.prod(arr, start = 2) print(product) Output: 240 Code #3: When the given iterable is empty Python3 # Python Program to explain math.prod() method # Importing math module import math # If the given input iterable # is empty, then this method # returns the start value # list arr = [] # Calculate the product of # of all elements present # in the given list product = math.prod(arr) print(product) # Tuple tup = () # Calculate the product of # of all elements present # in the given tuple product = math.prod(tup, start = 5) print(product) Output: 1 5 Reference: Python math library Create Quiz Comment I ihritik Follow 2 Improve I ihritik Follow 2 Improve Article Tags : Python Python math-library Python math-library-functions Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
