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']]
