Python: Tuples

Tuples are just like Python lists except that they are immutable. You can not add, delete or change elements after creating a Tuple instance. Tuples is a built-in data type in Python to store data collections. A tuple is a collection of values separated by commas and enclosed in parentheses.

Allow Duplicates: Tuples can contain duplicate values.
Ordered: Tuple items have a defined order, and that order remains constant.
Unchangeable: Once you create a tuple, you can’t add, remove, or modify its elements.

Remember, tuples are great for situations where you need an ordered, unchangeable collection of values.

Example

tpl = (1, 4, 5, True)
print (tpl [1])     # outputs 4
tpl [1] = 10        # throws an Exception of type TypeError
del tpl[1]           # throws an Exception of type TypeError

Accessing Items

You can access tuple items using indexing (starting from 0):

tpl = ("Aaliyan", "Muhammad", "Ali")

print(tpl[0])

Outputs => Aaliyan

Length of a Tuple

Use the len() function to find the number of items in a tuple:

print(len(tpl))

Outputs => 3

Creating a Tuple with One Item

If you want a single-item tuple, include a comma after the item:

single_item_tuple = ("Aaliyan",)

Data Types in Tuples

Tuples can hold different data types.

mixed_tuple = ("abc", 34, True)

Type of a Tuple

Python defines tuples as objects with the data type “tuple“

print(type(mytuple))

Outputs => <class ‘tuple’>
