<s>[INST] How can I reverse a list in python? How can I do this in python?
array = [0,10,20,40]
for (i = array.length() - 1 ;i >= 0; i--)

I need to have the elements of an array but from the end to the beginning.
 [/INST] >>> L = [0,10,20,40]
>>> L[::-1]
[40, 20, 10, 0]

Extended slice syntax is explained well here: http://docs.python.org/release/2.3.5/whatsnew/section-slices.html
By special request in a comment this is the most current slice documentation.
