How does Python know where the end of a function is?

I'm just learning python and confused when a "def" of a function ends?

I see code samples like:

def myfunc(a=4,b=6):
    sum = a + b
    return sum

myfunc()

I know it doesn't end because of the return (because I've seen if statements... if FOO than return BAR, else return FOOBAR). How does Python know this isn't a recursive function that calls itself? When the function runs does it just keep going through the program until it finds a return? That'd lead to some interesting errors.

Thanks

In my opinion, it's better to explicitly mark the end of the function by comment

def func():
     # funcbody
     ## end of subroutine func ##

The point is that some subroutine is very long and is not convenient to scroll up the editor to check for which function is ended. In addition, if you use Sublime, you can right click -> Goto Definition and it will automatically jump to the subroutine declaration.
