How to get last items of a list in Python?

Question

I need the last 9 numbers of a list and I'm sure there is a way to do it with slicing, but I can't seem to get it. I can get the first 9 like this:

num_list[0:9]

Any help would be great.

Answer 1

To get the last item of a list in Python you can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] 

>>> a 

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] 

>>> a[-9:] 

[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]
