Function Name: messageEncoder Parameters: message ( string ) Returns: encoded_message ( string ) Description: Write a function that takes in a message and outputs this message with the words at every other position beginning with the first one in upper case, and every other word in between in lower case. That is, the first word should be upper case, the second word lower case, the third word should be upper case, and so on. If the string passed in is the empty string, the function should return None. Hint: The string methods .lower() and .upper() might be useful. lower() ignores all punctua- tion to return a string with every letter in lowercase. upper() likewise ignores punctuation to return a string's uppercase representation. >>> message = "I woke up, couple mil on my plate" >>> print(messageEncoder(message)). I woke UP, couple MIL on MY plate >>> message = "I just went gave my mama a hundred" >>> print(messageEncoder(message)) I just WENT gave My mama A hundred messageEncoder("I just went gave my mama a hundred") (0.0/4.0) Test Failed: 'I just WENT gave MY Mama A hundred ' != 'I just WENT gave MY mama A hundred' - I just WENT gave MY mama A hundred Test, Estlandet sajust, WEAT.
