numpy string operations | split() function Last Updated : 25 Nov, 2019 Comments Improve Suggest changes Like Article Like Report 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.
