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.

Output:




Input array :  ['geeks for geeks']
Output splitted array:  [['geeks', 'for', 'geeks']]
