@YakutovDmitriy Task 3 was partially done, check, please

[YakutovDmitriy]

• squares, repeatntimes, evens and changecase are ok! But it is not necessary to use starmap to implement the latter one, you can use simple map
• Please do not use spaces in name of module. It becomes impossible to import

[YakutovDmitriy]

Forgot about extractnumbers. It is ok too

I do not remember if I've told you of not. Please rename files using the following symbols: english letters, digits, underscores. Other symbols make your file impossible for importing
