A Python list is a versatile data structure that allows you to group and store multiple items. Here are the key points about lists:

1. Creating a List:
   • You create a list by placing elements inside square brackets [], separated by commas.
   • For example:

ages = [19, 26, 29]
print(ages)  # Output: [19, 26, 29]

2. List Characteristics:

• Ordered: Lists maintain the order of elements.
• Mutable: You can change items after creation.
• Allows duplicates: Lists can contain duplicate values.

3. Accessing List Elements:

• Each element in a list has an associated index (starting from 0).
• You can access elements using these index numbers.
• Example:

languages = ['Python', 'Swift', 'C++']
print(languages[0])  # Output: Python
print(languages[2])  # Output: C++

4. Adding Elements:

• Use the append() method to add an element to the end of a list.
• Example:

fruits = ['apple', 'banana', 'orange']
fruits.append('cherry')
print(fruits)  # Output: ['apple', 'banana', 'orange', 'cherry']
