Python | sympy.euler() method Last Updated : 14 Jul, 2019 Comments Improve Suggest changes Like Article Like Report With the help of sympy.euler() method, we can find the Euler number and Euler polynomial in SymPy. euler(n) - Syntax: euler(n) Parameter: n - It denotes the nth Euler number. Returns: Returns the nth Euler number. Example #1: Python3 # import sympy from sympy import * n = 4 print("Value of n = {}".format(n)) # Use sympy.euler() method nth_euler = euler(n) print("Value of nth euler number : {}".format(nth_euler)) Output: Value of n = 4 Value of nth euler number : 5 euler(n, k) - Syntax: euler(n, k) Parameter: n - It denotes the order of the Euler polynomial. k - It denotes the variable in the Euler polynomial. Returns: Returns the expression of the Euler polynomial or its value. Example #2: Python3 # import sympy from sympy import * n = 5 k = symbols('x') print("Value of n = {} and k = {}".format(n, k)) # Use sympy.euler() method nth_euler_poly = euler(n, k) print("The nth euler polynomial : {}".format(nth_euler_poly)) Output: Value of n = 5 and k = x The nth euler polynomial : x**5 - 5*x**4/2 + 5*x**2/2 - 1/2 Example #3: Python3 # import sympy from sympy import * n = 4 k = 3 print("Value of n = {} and k = {}".format(n, k)) # Use sympy.euler() method nth_euler_poly = euler(n, k) print("The nth euler polynomial value : {}".format(nth_euler_poly)) Output: Value of n = 4 and k = 3 The nth euler polynomial value : 30 Comment R rupesh_rao Follow 0 Improve R rupesh_rao Follow 0 Improve Article Tags : Python SymPy Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 5 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 2 min read Python MySQL 9 min read Python Packages 10 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 4 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 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 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 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
