List Methods
List Methods
Python provides several methods that you can use to manipulate lists. These methods make it easy to modify, search, and manage lists effectively.
Let's explore some of the most commonly used methods:
append(): adds an item to the end of the list;remove(): removes the first occurrence of an item from the list;sort(): sorts the items of the list in ascending (or descending) order.
To use list methods in Python, you must invoke them on a list object using dot notation. This involves appending the method name to the list name followed by parentheses, as shown here: list_name.append("new element").
The next example will demonstrate how to apply various list methods using dot notation.
Imagine you need to update your store's inventory by adding new items and removing outdated ones.
Here's how you can do it using list methods:
1234567891011121314# Creating an inventory inventory = ["carrots", "bananas", "apples"] # Adding a new item inventory.append("oranges") # Removing an outdated item inventory.remove("bananas") # Sorting the inventory inventory.sort() # Checking the result print("Updated inventory:", inventory)
