Tuple<\/h2>\n\n\n\n
Tuples are used to store multiple items in a single variable.<\/p>\n\n\n\n
Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are\u00a0List,\u00a0Set, and\u00a0Dictionary, all with different qualities and usage.<\/p>\n\n\n\n
A tuple is a collection which is ordered and unchangeable<\/strong>.<\/p>\n\n\n\n
Tuples are written with round brackets.<\/p>\n\n\n\n
ExampleGet your own Python Server<\/h3>\n\n\n\n
Create a Tuple:<\/p>\n\n\n\n
thistuple = (\"apple\",\u00a0\"banana\",\u00a0\"cherry\")
print(thistuple)<\/code><\/pre>\n\n\n\n
\n\n\n\n
Tuple Items<\/h2>\n\n\n\n
Tuple items are ordered, unchangeable, and allow duplicate values.<\/p>\n\n\n\n
Tuple items are indexed, the first item has index [0]<\/code>, the second item has index [1]<\/code> etc.<\/p>\n\n\n\n
\n\n\n\n
Ordered<\/h2>\n\n\n\n
When we say that tuples are ordered, it means that the items have a defined order, and that order will not change.<\/p>\n\n\n\n
\n\n\n\n
Unchangeable<\/h2>\n\n\n\n
Tuples are unchangeable, meaning that we cannot change, add or remove items after the tuple has been created.<\/p>\n\n\n\n
\n\n\n\n
Allow Duplicates<\/h2>\n\n\n\n
Since tuples are indexed, they can have items with the same value:<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
Tuples allow duplicate values:<\/p>\n\n\n\n
thistuple = (\"apple\",\u00a0\"banana\",\u00a0\"cherry\",\u00a0\"apple\",\u00a0\"cherry\")
print(thistuple)<\/code><\/pre>\n\n\n\n
\n\n\n\n
\n\n\n\n
Tuple Length<\/h2>\n\n\n\n
To determine how many items a tuple has, use the len()<\/code> function:<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
Print the number of items in the tuple:<\/p>\n\n\n\n
thistuple = (\"apple\",\u00a0\"banana\",\u00a0\"cherry\")
print(len(thistuple))<\/code><\/pre>\n\n\n\n
\n\n\n\n
Create Tuple With One Item<\/h2>\n\n\n\n
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.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
One item tuple, remember the comma:<\/p>\n\n\n\n
thistuple = (\"apple\",)
print(type(thistuple))

#NOT a tuple
thistuple = (\"apple\")
print(type(thistuple))<\/code><\/pre>\n\n\n\n
\n\n\n\n
Tuple Items – Data Types<\/h2>\n\n\n\n
Tuple items can be of any data type:<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
String, int and boolean data types:<\/p>\n\n\n\n
tuple1 = (\"apple\",\u00a0\"banana\",\u00a0\"cherry\")\ntuple2 = (1,\u00a05,\u00a07,\u00a09,\u00a03)\ntuple3 = (True,\u00a0False,\u00a0False)\n\n<\/code><\/pre>\n\n\n\n
A tuple can contain different data types:<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
A tuple with strings, integers and boolean values:<\/p>\n\n\n\n
tuple1 = (\"abc\",\u00a034,\u00a0True,\u00a040,\u00a0\"male\")<\/code><\/pre>\n\n\n\n
\n\n\n\n
type()<\/h2>\n\n\n\n
From Python’s perspective, tuples are defined as objects with the data type ‘tuple’:<\/p>\n\n\n\n
<class ‘tuple’><\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
What is the data type of a tuple?<\/p>\n\n\n\n
mytuple = (\"apple\",\u00a0\"banana\",\u00a0\"cherry\")
print(type(mytuple))<\/code><\/pre>\n\n\n\n
\n\n\n\n
The tuple() Constructor<\/h2>\n\n\n\n
It is also possible to use the tuple() constructor to make a tuple.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n
Using the tuple() method to make a tuple:<\/p>\n\n\n\n
thistuple = tuple((\"apple\",\u00a0\"banana\",\u00a0\"cherry\"))\u00a0# note the double round-brackets
print(thistuple)<\/code><\/pre>\n\n\n\n
\n\n\n\n
Python Collections (Arrays)<\/h2>\n\n\n\n
There are four collection data types in the Python programming language:<\/p>\n\n\n\n
