Python | Find Mean of a List of Numpy Array Last Updated : 14 Mar, 2019 Comments Improve Suggest changes Like Article Like Report Given a list of Numpy array, the task is to find mean of every numpy array. Let's see a few methods we can do the task. Method #1: Using np.mean() Python3 1== # Python code to find mean of every numpy array in list # Importing module import numpy as np # List Initialization Input = [np.array([1, 2, 3]), np.array([4, 5, 6]), np.array([7, 8, 9])] # Output list initialization Output = [] # using np.mean() for i in range(len(Input)): Output.append(np.mean(Input[i])) # Printing output print(Output) Output: [2.0, 5.0, 8.0] Method #2: Using np.average() Python3 1== # Python code to find mean of # every numpy array in list # Importing module import numpy as np # List Initialization Input = [np.array([11, 12, 13]), np.array([14, 15, 16]), np.array([17, 18, 19])] # Output list initialization Output = [] # using np.mean() for i in range(len(Input)): Output.append(np.average(Input[i])) # Printing output print(Output) Output: [12.0, 15.0, 18.0] Comment More info E everythingispossible Follow Improve Article Tags : Python Python-numpy Python numpy-program 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 7 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 6 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 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
