Characteristic 1

Description

Ordered

• Lists maintain the order of elements as they are inserted.
• The order of elements in a list is determined by their indices, starting from 0.

Code

fruits = ["Apple", "Banana", "Cherry"]

print(fruits[0]) # Output: Apple (order is maintained)

Code

days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"]

print(days[0]) # Output: Monday

print(days[4]) # Output: Friday

Code

scores = [90, 85, 88, 92, 80]

print(scores) # Output: [90, 85, 88, 92, 80]

Characteristic 2

Description

Changeable/

Mutable

• can modify the elements after creation by adding, removing, or changing elements.

Code

numbers = [10, 20, 30]

numbers[1] = 25 # Modifying the second element

print(numbers) # Output: [10, 25, 30]

Code

names = ["Ali", "Sara", "John"]

names[1] = "Aisha" # Changing "Sara" to "Aisha"

print(names) # Output: ['Ali', 'Aisha', 'John']

Code

fruits = ["Apple", "Banana", "Cherry"]

fruits.append("Orange") # Adding an element

fruits.remove("Banana") # Removing an element

print(fruits) # Output: ['Apple', 'Cherry', 'Orange']

Characteristic 3

Description

Allow Duplicate

• Can creating a copy of an existing list.
• Can have duplicate values in the list

Code

names = ["Ali", "Sara", "Ali", "John"]

print(names) # Output: ['Ali', 'Sara', 'Ali', 'John']

Code

prices = [15.99, 25.50, 15.99, 30.00, 25.50, 45.75]

print(prices)

# Output: [15.99, 25.50, 15.99, 30.00, 25.50, 45.75]

Code

temperatures = [30.5, 32.0, 31.5, 30.5, 32.0, 31.5]

print(temperatures)

# Output: [30.5, 32.0, 31.5, 30.5, 32.0, 31.5]

Characteristic 4

Description

Supports Different Data Types

A list can store multiple data types in a single structure.

Code

mixed_list = [5, "Hello", 3.5, True]

print(mixed_list) # Output: [5, 'Hello', 3.5, True]

Code

info = ["Ali", 18, 3.5, True]

print(info) # Output: ['Ali', 18, 3.5, True]

Code

nested_list = [[1, 2, 3], ["A", "B", "C"], [True, False]]

print(nested_list[1]) # Output: ['A', 'B', 'C']

Characteristic 5

Description

Dynamic Size

Lists can grow or shrink by adding or removing elements.

Code

numbers = [1, 2, 3, 4, 5]

numbers.append(6) # Adding an element

numbers.remove(3) # Removing element 3

print(numbers) # Output: [1, 2, 4, 5, 6]

Code

colors = ["Red", "Blue"]

colors.append("Green") # Adding another color

print(colors) # Output: ['Red', 'Blue', 'Green']

Code

colors = ["Red", "Blue"]

colors.remove("Red") #Remove another color

print(colors) # Output: ['Blue']
