Python - cmath.isfinite() function Last Updated : 28 May, 2020 Comments Improve Suggest changes Like Article Like Report cMath module contains a number of functions which is used for mathematical operations for complex numbers. The cmath.isfinite() function is used to check whether the value is finite, or not. The value passed in this function can be int, float, and complex numbers. Syntax: cmath.isfinite(x) Parameter:This method accepts the following parameters. x :This parameter is the value to check for finite. Returns:This method returns a Boolean value. Below examples illustrate the use of above function: Example #1 : Python3 # Python code to implement # the isfinite()function # importing "cmath" # for mathematical operations import cmath # using cmath.isfinite() method val = cmath.isfinite(1 + 2j) print(val) Output: True Example 2: Python3 # Python code to implement # the isfinite()function # importing "cmath" # for mathematical operations import cmath # using cmath.isfinite() method val = cmath.isfinite(complex(3.0, float('inf'))) print(val) Output: False Comment More infoAdvertise with us S shubhamsingh10 Follow Improve Article Tags : Python Python math-library-functions Python Cmath-library Practice Tags : python Explore Python FundamentalsPython Introduction 3 min read Input and Output in Python 4 min read Python Variables 6 min read Python Operators 5 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 7 min read Python Functions 8 min read Recursion in Python 6 min read Python Lambda Functions 6 min read Python Data StructuresPython String 6 min read Python Lists 6 min read Python Tuples 6 min read Dictionaries in Python 7 min read Python Sets 10 min read Python Arrays 9 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 6 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 2 min read Python MySQL 9 min read Python Packages 12 min read Python Modules 7 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 11 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 6 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 15+ min read StatsModel Library- Tutorial 4 min read Learning Model Building in Scikit-learn 8 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 7 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 10 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 7 min read Python | Build a REST API using Flask 3 min read How to Create a basic API using Django Rest Framework ? 4 min read Python PracticePython Quiz 3 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
