Indexing is a very important concept not only with strings but with all the data types, such as lists, tuples, and dictionaries. bool. dict (since Python 3.9) It's not a widely known fact, but bitwise operators can perform operations from set algebra, such as union, intersection, and symmetric difference, as well as merge and update dictionaries.
