`numpy.core.defchararray.count(arr, sub, start=0, end=None)` is another function for doing string operations in numpy.It returns an array with the number of non-overlapping occurrences of substring sub in the range start to end.

Parameters:
arr : array_like of str or unicode.
sub : [str or unicode] The substring which to be searched.
start : [ int, optional] The starting location in each string.
end : [ int, optional] The ending location in each string.

Returns : [ndarray] the number of non-overlapping occurrences of substring sub.
