#Python's tuple

A tuple is an ordered collection of immutable values.

The literal syntax for a tuple uses parentheses () to wrap a group of values. For example:

students: tuple[str, str, str] = ("Tom", "Jerry", "Spike")

The type annotation tuple[str, str, str] indicates a tuple with three elements, each of type str.

Tuple elements can be of different types. For example:

student_info: tuple[str, int, str] = ("Yukari", 17, "female")

#Indexing

You can access elements in a tuple using square brackets [], just like in most programming languages. Python uses zero-based indexing:

students: tuple[str, str, str] = ("Tom", "Jerry", "Spike")
print(students)
print(students[0])
print(students[1])
print(students[2])

Once a tuple is created, it cannot be changed — you can't add, remove, or modify any element. However, you can reassign the variable. This doesn't change the tuple — it simply assigns a new value to the variable:

students: tuple[str, str, str] = ("Tom", "Jerry", "Spike")
students = 10

But as mentioned earlier, it's recommended not to change the variable type.

#Empty Tuples and Single-Element Tuples

You can create an empty tuple like this:

empty: tuple[()] = ()

To create a tuple with a single element, you need to include a trailing comma , to avoid ambiguity, since parentheses () have multiple uses in Python:

student: tuple[str] = ("Tom",)
