Python Tuples

Tuple Items — Data Types

Tuple functions in python can be of any data type:

Example

String, int and boolean data types:

tuple1 = (“apple”, “banana”, “cherry”)
tuple2 = (1, 5, 7, 9, 3)
tuple3 = (True, False, False)

Create Tuple Functions In Python With One Item

To create a tuple with only one item, you have to add a comma after the item, otherwise Python will not recognize it as a tuple.

Example

One item tuple, remember the comma:

thistuple = (“apple”,)
print(type(thistuple))

#NOT a tuple
thistuple = (“apple”)
print(type(thistuple))

Tuple Items

Tuple items are ordered, unchangeable, and allow duplicate values.

Tuple items are indexed, the first item has index [0], the second item has index [1] etc.

Ordered

When we say that tuples are ordered, it means that the items have a defined order, and that order will not change.

Unchangeable

Tuples are unchangeable, meaning that we cannot change, add or remove items after the tuple has been created.

Allow Duplicates

Since tuples are indexed, they can have items with the same value:

Example

Tuples allow duplicate values:

thistuple = (“apple”, “banana”, “cherry”, “apple”, “cherry”)
print(thistuple)

Tuple

Tuples are used to contain lots of items in a single and only variable.

Tuple is one of four built-in data types in Python used to contain stock of data, the other three are List, Set, and Dictionary, all with different form and usage.

A tuple is a collection which is ordered and unconvertible.

Tuples are written with round brackets.

Example

Create a Tuple:

thistuple = (“apple”, “banana”, “cherry”)
print(thistuple)
