def notStringContainingR(word): ''' - Return True when word is a string that contains no letter 'r' (or 'R') - It should work both for lower and upper case. - When word isn't a string or is an empty string (""), return True (because it is not a string contaning an R). - You can check if the word value is a string with type(word) == str ''' return "stub"
