Study Notes
List Manipulation in Python
- Use the
delstatement to remove an item from a list by specifying its index. - Example of
del list[index]operates directly on the list by removing the element located at that specific index.
Sequence Data Types
- Two key examples of sequence data types in Python are:
- Lists: Mutable sequences that can hold a collection of items.
- Tuples: Immutable sequences that can store a collection of items but cannot be changed after creation.
Clearing Lists
- The
clear()method is utilized to remove all items from a list, resulting in an empty list.
Removing Items with Return Values
- The
pop()method removes an item from a list at a given index and returns its value. - If no index is specified,
pop()removes and returns the last item in the list.

delstatement, leading to aNameErrorindicating that the variable is not defined.
