Study Notes
Sequences
- A sequence is an object that contains multiple items of data.
- Items in a sequence are stored one after another.
- Python provides different types of sequences, including lists and tuples.
Lists
- A list is a type of sequence that can contain multiple data items.
- An item in a list is called an element.
- The format of a list is:
list = [item1, item2, etc.]. - Lists can hold items of different types.
- The
printfunction can be used to display an entire list. - The
list()function can convert certain types of objects to lists.
Lists and Tuples
- The main difference between lists and tuples is that lists are mutable, while tuples are immutable.
