New submission from Liang Zhang: This was copied from Chapter 5 Data Structure in Python language tutorial.
The link I was looking for: https://docs.python.org/2.7/tutorial/datastructures.html Some thing might be incorrect and need you to update them in (5.1.4. List Comprehensions) It should be like this: ------------------start------------------ >>> vec = [-4, -2, 0, 2, 4] >>> # create a new list with the values doubled >>> [x*2 for x in vec] [-8, -4, 0, 4, 8] >>> # filter the list to exclude negative numbers >>> [x for x in vec if x >= 0] [0, 2, 4] >>> # apply a function to all the elements >>> [abs(x) for x in vec] [4, 2, 0, 2, 4] >>>>>>>>>>>It should be [0, 2, 4]<<<<<<<<<<< ------------------end------------------ ---------- assignee: docs@python components: Documentation messages: 234485 nosy: Liang.Zhang, docs@python priority: normal severity: normal status: open title: Documentation correction - 5.1.4.
