for i=morethanzero to n
for i in range(morethanzero, n): ...
for i= 5 to len(var)
for i in range(5, len(var)): ...
although range(len(var)) is usually not what you want, because you can just do:
for item in itertools.islice(var, 5, None): ...
or if you really do need the index too:
for i, item in itertools.islice(enumerate(var), 5, None): ...
