Оператор return используется для возврата из функции, т.е. для прекращения её работы и выхода из неё. При этом можно также вернуть некоторое значение из функции: def maximum (x, y): if x> y: return x elif x== y: return'. Числа равны.' else: return y print (maximum (2, 3)). Из функции можно вернуть только одно значение.

The function writes, i.e., "prints", a string in the console. The statement causes your function to exit and hand back a value to its caller. The point of functions in general is to take in inputs and return something. The statement is used when a function is ready to return a value to its caller.For example, here's a function utilizing both and :Now you can run code that calls foo, like so:If you run this as a script (e.g. a file) as opposed to in the Python interpreter, you will get the following output:I hope this makes it clearer. The interpreter writes return values to the console so I can see why somebody could be confused.Here's another example from the interpreter that demonstrates that:You can see that when is called from , 1 isn't written to the console. Instead it is used to calculate the value returned from . is a function that causes a side effect (it writes a string in the console), but execution resumes with the next statement. causes the function to stop executing and hand a value back to whatever called it.
