Python Lists
A list in Python is a data structure that holds an ordered collection of items, i.e., you can store a sequence of items in a list. These items can be of any type, and a list can contain items of different types.
Code Examples
empty_list = [ ] # An empty list
numbers_list = [1, 2, 3, 4, 5] # A list of integers
fruits_list = ["Apple", "Banana", "Cherry"] # A list of strings
mixed_list = [1, "Good Day !", 3.16, True] # A list with mixed data types
nested_list = [1, "Hi", [2, "Work till you can see yourself there"], True] # A list with another list as an item
Code Example
How to Access Elements from List
fruits = ["Apple", "Banana", "Cherry"]
print(fruits[0]) # Outputs: Apple
print(fruits[1]) # Outputs: Banana
print(fruits[-1]) # Outputs: Cherry, negative indexing starts from the end
How to perform List Slicing
Code Example
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print(numbers[2:5]) # Outputs: [3, 4, 5], includes the start index and excludes the end index
print(numbers[:5]) # Outputs: [1, 2, 3, 4, 5], if start index is not provided, it starts from the beginning
print(numbers[5:]) # Outputs: [6, 7, 8, 9, 10], if end index is not provided, it goes up to the end
How to Append Elements in List-Adding Elements to List
Code Example
fruits = ["Apple", "Banana", "Cherry"]
fruits.append("Dragonfruit") # Add a single item to the end
print(fruits) # Outputs: ['Apple', 'Banana', 'Cherry', 'Dragonfruit']
more_fruits = ["Elderberry", "Fig", "Grape"]
fruits.extend(more_fruits) # Add multiple items to the end
print(fruits) # Outputs: ['Apple', 'Banana', 'Cherry', 'Dragonfruit', 'Elderberry', 'Fig', 'Grape']
fruits.insert(0, "Avocado") # Insert 'Avocado' at position 0
print(fruits) # Outputs: ['Avocado', 'Apple', 'Banana', 'Cherry', 'Dragonfruit', 'Elderberry', 'Fig', 'Grape']
How to Remove Elements from List
Code Example
fruits = ["Apple", "Banana", "Cherry"]
fruits.remove("Banana") # Remove a specific item
print(fruits) # Outputs: ['Apple', 'Cherry']
removed_fruit = fruits.pop(0) # Remove the item at position 0 and get its value
print(removed_fruit) # Outputs: 'Apple'
print(fruits) # Outputs: ['Cherry']
