Notice that all of the data in the inner lists are represented as strings. You are to write the function convert_data, which should make modifications to the inner lists according to the following rules: If and only if a string represents a whole number (ex: '3' or '3.0'), convert the string to an int. If and only if a string represents a number that is not a whole number (ex: '3.14'), convert the string to a float. Otherwise, leave the string as a str.HINT: The provided helper function is_number may be used (attached image).

QUESTION 4 This is a MULTIPLE ANSWER question, which means you are able to select one or more answers as being correct. Note that this does not necessarily mean that there are multiple correct answers. In any case, select all the answers you believe are correct. (NB: There are no part marks awarded for multiple answer questions.) There is a non-empty Python list of integers called numbera whose values are all in the range -maxaize to maxaize, inclusive. The following piece of code causes the SMALLEST value in list numbers to be stored in the variable answer: best - maxsize t a very large integer for number in numbers: if number number: t a very large integer best = number answer = best + a very small integer best - -maxsize for number in numbers: if best best: best = number answer= best best = -maxsize * a very small integer for number in numbers: if best > number: best - number answer best
