Because the original language uses class declaration rather than normal function declarations. And the translations follow that pattern, too late to change that as all solutions will be invalidated ...

Why most of the solution are using class?

You don't have to, you could use the fully qualified name instead of using the System namespace.

Can someone explain to me why i have to import the systems library its getting ridiculouse

In python, the print function actually returns None. So, when you do return print("blah"), it will print "blah" to stdout, but the value that the function returns is None. If you want to check for yourself, you can run print(print("something)) and you'll see that it prints "something" and then one line afterwards it prints None.

Tests on codewars do not read stdout, so the tests are blind to anything that you print out. The tests will call your function and use the value that your function returns to the tests. If you're returning print("whatever"), the only value that the tests ever see is None.

Ah I see, would just a for loop comparing the current value vs lowest known value be less performance expensive or is there some fancy built in python function to do that?

Yes, this is a bad method because sorting is more expensive (i.e. slower and requires more computing power) than other methods, which are also simpler code-wise.
