Concept: Slicing

Slicing allows you to select items from a list or string by specifying a range of indices. You can use the syntax list[start:end] to get items from the start index up to, but not including, the end index. You can also omit the start or end index to slice from the beginning or to the end of the list/string, respectively. Additionally, you can specify a step value with list[start:end:step] to skip items in the range.
