What is the difference between a list and a tuple?

Question

Khushi Singh · Answer

Python contains both
lists and tuples as sequence data types, which are used to organize item collections. The fundamental variations between these data types affect operational functionality, together with execution speed.
The key difference centers on their ability to change data. Additions and modifications, and element removal capabilities are possible in a list due to its mutable nature after its initial creation. A tuple remains unalterable because it retains its original elements after its definition process. Immutability in tuples ensures better safety during fixed data handling and enables faster performance because it reduces memory management requirements.
A list can undergo modifications according to this example.
my_list = [1, 2, 3]
my_list.append(4)  # Adds 4 to the list
my_list[0] = 10    # Changes the first element to 10
Whereas a tuple remains unchanged after creation:
my_tuple = (1, 2, 3)
# my_tuple[0] = 10  # This would raise an error
A list requires square brackets ([]) for its definition, whereas tuples need parentheses (()) to create them. Dynamic resizing occurs through lists because their items support change, yet tuples keep their initial dimensions static.
Selection of tuples prevails over lists for iteration operations because of their immutability property, which results in data preservation requirements. Data storage becomes more efficient through the use of tuples since they consume less memory than lists.
Systems frequently select lists when data needs regular updates, while tuples serve as a preferred data storage method when the need arises to maintain data stability. Tuples or lists should be selected based on which requirement stands as more important between flexibility and smooth operational performance.
