Question

def change_type(info: List[list]) -> None:
""" Modify info to a float if and only if it represents a number that is not
a whole number(a float), and convert info to an int if and only if it represents a
whole number, keep everythingelse as a string.

>>> i = [['apple', '888', 'School', '111.1']]
>>> change_type(i)
>>> i

  [['apple', 888, 'School', '111.1']]

Please help! Write as little code as possible!

Please only use if statements, nested loop and lists to solve this question.

def change_type(info):
    newList = []

    # iterating list through sub lists
    for subList in info:

        # initializing empty list
        temp = []
        # iterating though every element in sub list
        for element in subList:

            # checking if number is numeric or not
            # if numeric converted into integer and appended
            # else numeric is converted to float and appended
            if element.isnumeric():
                if int(element) >= 0:
                    temp.append(int(element))
                else:
                    temp.append(float(element))
            else:
                temp.append(element)

        # appending sublist to newList
        newList.append(temp)
        # returning newlist

    return newList
