    I’m voting to close this question because the questioner just needs to turn to tutorials and not this site. Commented Nov 14 at 16:31

    (1, 20) are the arguments to the range function. This is common syntax in most programming languages, you need to learn the basics before you can post reasonable questions here. Commented Nov 14 at 16:33
