Instead of using the while loop and a counter, you can use the range() 
function.  Using range() and string formatting you could to something like:

def ZeroThrough255():
	for num in range(256):
		print "%03d" % num

which, using a list comprehension and the string join() function, could also 
be written as:

def ZeroThrough255():
	print "\n".join(["%03d" % num for num in range(256)])
