Use the bracket notation for slicing with the start and end position identifiers. For example,
word[i:j] returns the substring starting from index

You can also skip the position identifier before or after the slicing colon. This indicates that the slice starts from the first or last position, respectively. For example,
word[:i] + word[i:] returns the same string as
