how to input numbers after running

Question

i only have some basic ideas of python，i can only input numbers in source code

Answer 1

What do you mean by that? Do you mean after you running the program how you can input a statement?

Answer 2

The only way to input something is if you put something like
user=input("Input Statement: ")

Or if you need a number inputed and defined as a number you put

user=float(input)("Enter a Number"))

Or if you need to put more than one input you put a space after each input. For example:

John Timmy Hello

That's three input's because there's a space.
Hope that helps at all
