(python) Write a function jscore(s1, s2) that takes two strings s1 and s2 as inputs and returnsthe Jotto score of s1 compared with s2 i.e., the number of characters in s1 that are shared by s2. The positions and the order of the shared characters within each string do not matter. Repeated letters are counted multiple times, as long as they appear multiple times in both strings. For example:

>>> jscore('diner', 'syrup') # just the 'r' 1
