List slicing allows you to extract a portion of a list or another sequence type by specifying start, end, and optional step values. This feature is very useful for extracting sub-sequences.

my_list[start:end:step]

Example:

my_list = [0, 1, 2, 3, 4, 5]
sub_list = my_list[1:4]
print(sub_list)  # Output: [1, 2, 3]
