In python

C. Define a function called only uses_letters_from() that takes two strings and returns True if the first string only contains characters that are also in the second string. Or to put it another way: it should return False if there are any characters in the first string that are not in the second string (Note: it's okay if there are characters in the second string that aren't in the first string.) For example, only uses_letters_from("boffo", "foobar") should return True, but only_uses_letters_from("zaxy", "xyzzy") should return False Hint: we recommend using the in operator here, as introduced in Reading Assignment 06: this is not the same thing as the "in" that shows up as part of the start of a for loop. If you're up for a bigger challenge, you could try to do this without using the in operator (you'll need nested for loops for that)
