numpy string operations | split() function Last Updated : 25 Nov, 2019 Comments Improve Suggest changes Like Article Like Report numpy.core.defchararray.split(arr, sep=None, maxsplit=None) is another function for doing string operations in numpy.It returns a list of the words in the string, using sep as the delimiter string for each element in arr. Parameters: arr : array_like of str or unicode.Input array. sep : [ str or unicode, optional] specifies the separator to use when splitting the string. maxsplit : how many maximum splits to do. Returns : [ndarray] Output Array containing of list objects. Code #1 : Python3 # Python program explaining # numpy.char.split() method # importing numpy import numpy as geek # input array in_arr = geek.array(['geeks for geeks']) print ("Input array : ", in_arr) # output array out_arr = geek.char.split(in_arr) print ("Output splitted array: ", out_arr) Output: Input array : ['geeks for geeks'] Output splitted array: [['geeks', 'for', 'geeks']] Code #2 : Python3 # Python program explaining # numpy.char.split() method # importing numpy import numpy as geek # input array in_arr = geek.array(['Num-py', 'Py-th-on', 'Pan-das']) print ("Input array : ", in_arr) # output array out_arr = geek.char.split(in_arr, sep ='-') print ("Output splitted array: ", out_arr) Output: Input array : ['Num-py' 'Py-th-on' 'Pan-das'] Output splitted array: [['Num', 'py'] ['Py', 'th', 'on'] ['Pan', 'das']] Code #3 : Python3 # Python program explaining # numpy.char.split() method # importing numpy import numpy as geek # input array in_arr = geek.array(['Num-py', 'Py-th-on', 'Pan-das']) print ("Input array : ", in_arr) # output array when maximum splitting # of every array element is 1 out_arr = geek.char.split(in_arr, sep ='-', maxsplit = 1) print ("Output splitted array: ", out_arr) Output: Input array : ['Num-py' 'Py-th-on' 'Pan-das'] Output splitted array: [['Num', 'py'] ['Py', 'th-on'] ['Pan', 'das']] Comment More info J jana_sayantan Follow Improve Article Tags : Python Python-numpy Python numpy-String Operation 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 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 7 min read Python Functions 5 min read Recursion in Python 6 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 5 min read Python Tuples 4 min read Dictionaries in Python 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
