Python Tuple

In Python, a tuple is similar to a list, but it is immutable, meaning that you cannot modify its contents once it has been created. Tuples are often used to represent fixed collections of related data, such as a date or a point in two-dimensional space.

Here's an example of how to create a tuple in Python:

my_tuple = (1, 2, 3, "four", 5.0)

In this example, we've created a tuple with five elements: the integers 1, 2, and 3, the string "four", and the floating-point number 5.0.

You can access elements of a tuple using the same indexing syntax as with lists:

print(my_tuple[0])    # prints 1
print(my_tuple[3])    # prints "four"

You can also use negative indexing to access elements from the end of the tuple:

print(my_tuple[-1])   # prints 5.0
print(my_tuple[-2])   # prints "four"

Because tuples are immutable, you cannot add or remove elements from them. However, you can create a new tuple by concatenating two or more tuples:

new_tuple = my_tuple + (6, 7, 8)

This creates a new tuple containing the elements of the original tuple, followed by the integers 6, 7, and 8.

You can also use tuple unpacking to assign the elements of a tuple to individual variables:

a, b, c, d, e = my_tuple

This assigns the first five elements of the tuple to the variables a, b, c, d, and e, respectively.

These are just a few examples of the many ways that you can work with tuples in Python. Tuples are a useful data type when you need to represent a fixed collection of related data that should not be modified.
