Input allows you to ask the user to do something.
In Portable Python it pops up as a great user input box.
It can be as simple as pausing the program
You can ask the user to make a decision
Note that there is no guarantee that your user will type s or t.
If you want your user to input a whole number (not a negative number or a decimal fraction) you have to add int)
This could then be printed, checked to see if it is correct or used in another way.
Note the extra set of parenthesis (brackets) have to be closed
If you want your user to input a decimal fraction or negative number you need to add float
