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--
