python slice index code example

Example 1: python list slice sybtax

# [start:stop:step]
# for example ...
l = [1, 2, 3, 4, 5]
l[1:4] # elements from 1 (inclusive) to 4 (exclusive)
l[2:5:2] # elements from 2 (inclusive) to 5 (exclusive) going up by 2

Example 2: list slicing in pandas

>>> nums = [10, 20, 30, 40, 50, 60, 70, 80, 90]
>>> some_nums = nums[2:7]
>>> some_nums
[30, 40, 50, 60, 70
