Answer by Number File for Calling a function of a module by using its name (a string)

This is a simple answer, this will allow you to clear the screen for example. There are two examples below, with eval and exec, that will print 0 at the top after cleaning (if you're using Windows, change clear to cls, Linux and Mac users leave as is for example) or just execute it, respectively.

eval("os.system(\"clear\")")
exec("os.system(\"clear\")")
