The cmath.phase() function is used to get the phase of a complex number. The value passed in this function can be int, float, and complex numbers. Syntax: cmath.phase(x) Parameter:This method accepts the following parameters. x :This parameter is the number to find the phase of. Returns:This method returns a float value that represent the phase of a complex number. Below examples illustrate the use of above function: Example #1 : Python3 # Python code to implement # the phase()function # importing "cmath" # for mathematical operations import cmath # using cmath.phase() method val = cmath.phase(1) print(val) Output: 0.0 Example 2: Python3 # Python code to implement # the phase()function # importing "cmath" # for mathematical operations import cmath # using cmath.phase() method val = cmath.phase(1 + 4j) print(val) Output: 1.3258176636680326 Comment More info S shubhamsingh10 Follow Improve Article Tags : Python Python math-library-functions Python Cmath-library Explore Python FundamentalsPython Introduction 3 min read Input and Output in Python 4 min read Python Variables 5 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 5 min read Recursion in Python 6 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 5 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 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 3 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 7 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
