Python reverse a list

You can make use of the reversed function for this as:

>>> array=[0,10,20,40]
>>> for i in reversed(array):
...     print(i)

Note that reversed(...) does not return a list. You can get a reversed list using list(reversed(array)).

According to the above link to, "Compared to extended slicing, such as range(1,4)[::-1], reversed() is easier to read, runs faster, and uses substantially less memory.
