Python 3 please

Write a function is_Subset(s1, s2) that takes two strings, and checks whether the first string is a subset of the second string or not. It returns True or False accordingly; A string si is said to be a subset of a string s2, if all the characters of si are included in s2. You may assume all the characters are lower case letters. For example: Test Result print(is_Subset("ant", "pomegranate")) True print(is_Subset("abc", "pomegranate")) False print(is_Subset("tent", "pomegranate")) True print(is_Subset("", "abc")) True
