numpy string operations | split() function

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 :

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']]
