Pass by reference ?

Sorry, this function is not a good demonstration.
w is a reference to whatever is passed in.
Then you are making w a reference to None.
What you should try is w.append(5), or something

Try thusly:
def Appender(w):
	print w
	w.append(5)
	print w
Now, let's call this:

x=[]
Appender(x)

You'll see:
[]
[5]
Then, if you print x, you'll see:
[5]

Thus, we passed it by reference, because it modified the original.

Bad example.
