Difference Between a Tuple and List in Python

Показать описание
In Python, both tuples and lists are used to store collections of items, but they have some key differences in terms of their syntax, mutability, and usage.
Syntax:
A tuple is defined using parentheses, while a list is defined using square brackets. For example:
my_tuple = (1, 2, 3)
my_list = [1, 2, 3]
Mutability:
Tuples are immutable, which means that once a tuple is created, its contents cannot be modified. In contrast, lists are mutable, which means that you can add, remove, or modify elements within a list. For example:
my_tuple[0] = 4 # will raise a TypeError
my_list[0] = 4 # will modify the first element of the list
Usage:
Tuples are typically used to store related pieces of data that should not be modified, such as a point in 2D space, or a person's name and age. Lists, on the other hand, are used to store collections of data that may need to be modified, such as a list of users or a list of tasks to be completed.
In addition to these differences, there are some performance differences between tuples and lists. Tuples are generally faster and consume less memory than lists, but this difference is usually only noticeable for very large collections of data.
Overall, the choice between using a tuple or a list depends on the specific requirements of the code. If the data should be immutable, use a tuple, and if it needs to be mutable, use a list.
