4. Tuple Input a) Write a function called input tuple (in a new file p4py) that reads from the terminal a sequence of objects with types provided by a tuple given as parameter and that returns the sequence of objects read as a tuple. The function will iterate throush the types tuple and will try to parse the inout string based on the types The function takes the following parameters prompt: a string to be displayed as input prompt 2. types atuple of type objects that must match the types of the data entered by the user and returmed by the function. The only types supported are int floot, str, boo 1 sep: a string that separates the input objects, with default value The function returns one ol ifparsing the data from the user acording to the types tuple succeeds, then it returns the tuple with the converted data to Python objects, if parsing the data from the user according to the types tuple fails, then it returns the empty tuple () · Error handling the function must not raise/throw emors related to parsing or input/read operations Use proper error handling with try/except.h se o' any error, print an error message to the terminal nd return the empty tuple (0 Hore is a surnesful eample on how thr function can be used: stutent tup -input tupieEnter tirz namelax nme, zReotio l, tuizime Ibool Istr, str, toa. nt, ool), ?this is the tuple with expected types is the separatee charonef on the inde ine The function displays the prompt: Enter first name, last name, age a, D ), ulltine (ol The user enters the string: Sponeebob,squarepants,23 5,1,True". Then, the tuple returned will be equal to ("Spongebob", "Squarepants", 23.5?1, True. Here is an example when parsing based on the types tuple fails: The funsiun call is the sare as above, but the user entess: "Spongebab S Notce that the token count is less than required - a separator is missine, The function retuns Another example ot failure is if the user types: "KeitnRupert,Murdoch,20,10010 false". The function exgects a float for the 3 object, butgets instead a string that cant be converted to tloat.
