5.1 The input function

Another very useful function is input: it takes a string that it prints on the screen (the user’s prompt), and returns a string with what the user typed on the keyboard until they pressed the RETURN or ENTER key. Run the code below and type in your name, followed by RETURN or ENTER.

Interactive feature not available in single page view (see it in standard view).

Note that input always returns a string, even if the user typed in a number. To see the implications of that, run the code below and type in your birth year.

Interactive feature not available in single page view (see it in standard view).

The computer reports a type error, because the code is mixing two different types of data. It is trying to subtract the string returned by input from the number 2015.
