numpy string operations | split() function (original) (raw)

Last Updated : 25 Nov, 2019

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 :

import numpy as geek

in_arr = geek.array([ 'geeks for geeks' ])

print ( "Input array : " , in_arr)

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 :

import numpy as geek

in_arr = geek.array([ 'Num-py' , 'Py-th-on' , 'Pan-das' ])

print ( "Input array : " , in_arr)

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 :

import numpy as geek

in_arr = geek.array([ 'Num-py' , 'Py-th-on' , 'Pan-das' ])

print ( "Input array : " , in_arr)

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']]
