numpy.ascontiguousarray() in Python Last Updated : 16 Nov, 2021 Suggest changes Share 2 Likes Like Report numpy.ascontiguousarray()function is used when we want to return a contiguous array in memory (C order). Syntax : numpy.ascontiguousarray(arr, dtype=None) Parameters : arr : [array_like] Input data, in any form that can be converted to an array. This includes scalars, lists, lists of tuples, tuples, tuples of tuples, tuples of lists, and ndarrays. dtype : [str or dtype object, optional] Data-type of returned array. Return : ndarray Contiguous array of same shape and content as arr, with type dtype if specified. Code #1 : List to array Python # Python program explaining # numpy.ascontiguousarray() function import numpy as geek my_list = [100, 200, 300, 400, 500] print ("Input list : ", my_list) out_arr = geek.ascontiguousarray(my_list, dtype = geek.float32) print ("output array from input list : ", out_arr) Output : Input list : [100, 200, 300, 400, 500] output array from input list : [ 100. 200. 300. 400. 500.] Code #2 : Tuple to array Python # Python program explaining # numpy.ascontiguousarray() function import numpy as geek my_tuple = ([2, 6, 10], [8, 12, 16]) print ("Input tuple : ", my_tuple) out_arr = geek.ascontiguousarray(my_tuple, dtype = geek.int32) print ("output array from input tuple : ", out_arr) Output : Input tuple : ([2, 6, 10], [8, 12, 16]) output array from input tuple : [[ 2 6 10] [ 8 12 16]] Code #3 : Scalar to array Python # Python program explaining # numpy.ascontiguousarray() function import numpy as geek my_scalar = 100 print ("Input scalar : ", my_scalar) out_arr = geek.ascontiguousarray(my_scalar, dtype = geek.float32) print ("output array from input scalar : ", out_arr) print(type(out_arr)) Output : Input scalar : 100 output array from input scalar : [ 100.] class 'numpy.ndarray' J jana_sayantan Follow 2 Article Tags : Python Python-numpy Python numpy-arrayCreation 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 My Profile ${profileImgHtml} My Profile Edit Profile My Courses Join Community Transactions Logout Like
