Tuples are used to store multiple items in a single variable.
A tuple is a collection which is ordered and unchangeable.
Tuples are written with round brackets.
Example-
Create a Tuple:
thistuple = ("apple", "banana", "cherry")
print(thistuple)
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.
When we say that tuples are ordered, it means that the items have a defined order, and that order will not change.
Tuples are unchangeable, meaning that we cannot change, add or remove items after the tuple has been created.
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)
To determine how many items a tuple has, use the len() function:
Example-
Print the number of items in the tuple:
thistuple = ("apple", "banana", "cherry")
print(len(thistuple))
Tuple items 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)
From Python's perspective, tuples are defined as objects with the data type 'tuple':
Example-
What is the data type of a tuple?
mytuple = ("apple", "banana", "cherry")
print(type(mytuple))
You can access tuple items by referring to the index number, inside square brackets:
Example-
Print the second item in the tuple:
thistuple = ("apple", "banana", "cherry")
print(thistuple[1])
You can loop through the tuple items by using a for loop.
Example-
Iterate through the items and print the values:
thistuple = ("apple", "banana", "cherry")
for x in thistuple:
print(x)
