Quick Preview

fruits = ["apple", "banana", "cherry"]

fruits.append("date")
fruits.sort()

print(fruits)       # ['apple', 'banana', 'cherry', 'date']
print(fruits[0])    # apple
print(len(fruits))  # 4

Lists are mutable — you can add, remove, and change elements after creation. This makes them fundamentally different from strings and tuples.
