A sequence is an iterable, which means you can iterate through it. A sequence has a length, which means you can pass it to len() to get its number of elements. An element of a sequence can be accessed based on its position in the sequence using an integer index. You can use the square bracket notation to index a sequence.
Lists, tuples, and strings are among Python's most basic data types. Even though they're different types with distinct characteristics, they have some common traits.
