Return statement question

[Gregoire Welraeds]

Hi Pi(th)oneers,

I though that every function had a return statement...
But I found something that looks strange to me.
In the following piece of code:

def func1():
	...
#	there is no return here
def func2():
	...
#	there is no return here
def func3():
	...
#	there is no return here

if __name__ == '__main__':
	func1()
	func2()
	func3()

I do not have an explicit call to the return statement. and the process
goes from func1() to func3().
Now imagine that func3 has one arg which is a returned value from func2 
like this :
def func1():
	...
#	there is no return here
def func2():
	...
	return some_value
def func3(sv):
	...
#	there is no return here

if __name__ == '__main__':
	func1()
	val= func2()
	func3(val)

In this cas func3 is never executed...

why ?
