numpy string operations | split() function
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 :
# Python program explaining# numpy.char.split() method # importing numpy import numpy as geek # input array in_arr = geek.array(['Lazyroar for Lazyroar'])print ("Input array : ", in_arr) # output array out_arr = geek.char.split(in_arr)print ("Output splitted array: ", out_arr) |
Output:
Input array : ['Lazyroar for Lazyroar'] Output splitted array: [['Lazyroar', 'for', 'Lazyroar']]
Code #2 :
# 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 :
# 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 1out_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']]
