return statement

• With return, functions send returns value back to the caller code.
• Types:
  1. Explicit return statement: It terminates a function execution and sends the return value back to the caller code.
  2. Implicit return statement:** If you don’t write a return statement, it returns None.

Short-circuiting loops

• A return statement inside a loop performs some kind of short-circuit.
• It breaks the loop execution and makes the function return immediately.

Using return in generator functions

def gen():
    yield 1
    yield 2
    return 3 # indicates that the generator is done and makes the generator raise a `StopIteration`
