Answer 1

If you are sure that you can enter the input data properly, there is some code that can handle input elements as different data types. For a practical use to enter different data types, i would prefer to get them as string, and convert them in the next step in a try... except... block.
This is the code that can handle such a task:
#Created by Amzat:
# best solution with flexible conversion during input
#types = (int, int, str) # can also use float
# Enter 7 9 ABC => [4, 7, 'ABC']
inp = [typ(value) for typ, value in zip((int, int, str), input().split())]

Answer 2

As HonFu pointed out input is always str
Python 3 has a built-in function input() to accept user input. But Python 3 doesn’t evaluate the data received with input function, i.e., Python input() function always converts the user input into a string then returns it to the calling program. i.e., the type of user input is still a string.

Answer 3

Input in Python is always str.
If you need to convert all or part of it to something else, you need to do it manually afterwards.

Answer 4

Give a sample input.
My first thought is to use a regular expression.
