def char InWord (word, char): -charInWord() takes in a parameter word and another parameter char and determines whether char is contained in word. -If word is not a string type, or if char is not a string type, the function should return None. -If word contains the letter char, the function should return True. Otherwise, it should return false. - Note: When char is of type string, it should be of length 1. For example, char will be a single letter like "a" or "z." We will not test for cases where char is more than one character, like char = "ab" -*** Note: you will need to use a while loop and string indexing.*** **** You will not get full credit if you use other loops or the in operator. *** return "stub
