[Tutor] who makes FOR loop quicker

To pass by reference or by copy of - that is the question from hamlet. 
("hamlet" - a community of people smaller than a village python3.4-linux64)

xlist = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
i = 0
for x in xlist:
	print(xlist)
	print("\txlist[%d] = %d" % (i, x))
	if x%2 == 0 :
		xlist.remove(x)
	print(xlist, "\n\n")
	i = i + 1

So, catch the output and help, PLEASE, me improve the answer:
Does it appropriate ALWAYS reevaluate the terms of the list on each 
iteration?
But if I want to pass a copy to FOR instead of a reference (as seen from 
an output) and reduce unreasonable reevaluation, what I must to do for that?
