	Too late... Any assertion error will occur when you CALLED the
function. Here you are just retrieving the value the function returned (and
since they don't return anything, that value is None) and immediately
throwing it away.


testList = [print1, print2, print3]	#do NOT CALL functions

for test in testList:
	try:
		test()		#call the function now
	except ...		#whatever you intend to handle
