for for loops for example ( never apologize for my puns)you can even use negative number for the step argument to make the for loop count down instead of up for in range( - - )print(ithis for loop would have the following output running for loop to print with range( - - should print from five down to zero importing modules all python programs can call basic set of functions called built-in functionsincluding the print()input()and len(functions you've seen before python also comes with set of modules called the standard library each module is python program that contains related group of functions that can be embedded in your programs for examplethe math module has mathematicsrelated functionsthe random module has random number-related functionsand so on before you can use the functions in moduleyou must import the module with an import statement in codean import statement consists of the followingthe import keyword the name of the module optionallymore module namesas long as they are separated by commas once you import moduleyou can use all the cool functions of that module let' give it try with the random modulewhich will give us access to the random randint(function enter this code into the file editorand save it as printrandom pyimport random for in range( )print(random randint( )flow control
