Python | Numpy numpy.transpose() Last Updated : 07 Mar, 2022 Comments Improve Suggest changes Like Article Like Report With the help of Numpy numpy.transpose(), We can perform the simple function of transpose within one line by using numpy.transpose() method of Numpy. It can transpose the 2-D arrays on the other hand it has no effect on 1-D arrays. This method transpose the 2-D numpy array. Parameters: axes : [None, tuple of ints, or n ints] If anyone wants to pass the parameter then you can but it's not all required. But if you want than remember only pass (0, 1) or (1, 0). Like we have array of shape (2, 3) to change it (3, 2) you should pass (1, 0) where 1 as 3 and 0 as 2.Returns: ndarray Example #1 : In this example we can see that it's really easy to transpose an array with just one line. Python3 # importing python module named numpy import numpy as np # making a 3x3 array gfg = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) # before transpose print(gfg, end ='\n\n') # after transpose print(gfg.transpose()) Output: [[1 2 3] [4 5 6] [7 8 9]] [[1 4 7] [2 5 8] [3 6 9]] Example #2 : In this example we demonstrate the use of tuples in numpy.transpose(). Python3 # importing python module named numpy import numpy as np # making a 3x3 array gfg = np.array([[1, 2], [4, 5], [7, 8]]) # before transpose print(gfg, end ='\n\n') # after transpose print(gfg.transpose(1, 0)) Output: [[1 2] [4 5] [7 8]] [[1 4 7] [2 5 8]] Method 2: Using Numpy ndarray.T object. Python3 # importing python module named numpy import numpy as np # making a 3x3 array gfg = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) # before transpose print(gfg, end ='\n\n') # after transpose print(gfg.T) Output[[1 2 3] [4 5 6] [7 8 9]] [[1 4 7] [2 5 8] [3 6 9]] Comment More info J jitender_1998 Follow Improve Article Tags : Python Python-numpy 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
