Syntax : Numpy.expand_dims() Return : Return the expanded array. Example #1 : In this example we can see that using Numpy.expand_dims() method, we are able to get the expanded array using this method. Python3 1=1 # import numpy import numpy as np # using Numpy.expand_dims() method gfg = np.array([1, 2]) print(gfg.shape) gfg = np.expand_dims(gfg, axis = 0) print(gfg.shape) Output : (2, ) (1, 2) Example #2 : Python3 1=1 # import numpy import numpy as np # using Numpy.expand_dims() method gfg = np.array([[1, 2], [7, 8]]) print(gfg.shape) gfg = np.expand_dims(gfg, axis = 0) print(gfg.shape) Output : (2, 2) (1, 2, 2) Create Quiz Comment J jitender_1998 Follow 3 Improve J jitender_1998 Follow 3 Improve Article Tags : Python Python numpy-Basics 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 2 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
