Introduction to Python Tuples

Creating a tuple

We can create an empty tuple in python by writing nothing in the parentheses.

Example 1

Input:

tup1 = ()
print(tup1)

 

Output

()

 

To create a tuple with a single element, we have to insert a comma at the end.

 

Example 2

Input:

tup1 = (“Hello”,)
print(type(thistuple))

 

Output

 

<class 'tuple'>

 

To create a tuple with multiple data type values in one variable.

 

Example 3

Input:

tup1 = ("ab", 314, True, 40, "Hello")
print(tup1)

 

Output

 

('ab', 314, True, 40, 'Hello')

 

You can compile it with online python compiler.

Accessing of elements in the tuple

We can assess the elements of the tuple using square brackets. Let's go through the below example for improving your visualization.

 

Example

Input:

tup1 = ('Hello', 'Wolrd', 20)
print tup1[0]
print tup1[2]

 

Output

 

Hello
20

 

Deleting a tuple

Removing elements from the tuple is not possible. So to remove an entire tuple explicitly, use the del statement.

 

Example

Input:

tup1 = (‘Hello’, 'World', 20)
print tup1;
del tup1;
print tup1;

 

Output

 

(‘Hello’, 'World', 20)
Traceback (most recent call last):
   File "example.py", line 9, in <module>
      print tup1;
NameError: name 'tup1' is not defined

Slicing in a tuple

We can access the elements of a particular index using slicing. It is used to fetch a range of items. Slicing can be represented in the below format:

[start:stop: step], where step part is not necessary to be mentioned The compiler considers it '1' by default if we do not mention the step part.

 

Example 1

Input:

tup = (22, 3, 45, 4, 2, 56, 890, 1)
print(tup[1:5])

 

Output

(3, 45, 4, 2)

 

Example 2

Input:

tup = (22, 3, 45, 4, 2, 56, 890, 1)
print(tup[:3])

 

Output

(22, 3, 45)

Concatenation in a tuple

To concatenate two tuples, we can use the ‘+’ operator.

Example

Input:

tup1 = ('Coding', 'Ninjas')
tup2 = ('Hello', 1)
print(tup1+tup2)

 

Output

(Coding, Ninjas, Hello, 1)

 

Finding the length of the tuple

To determine the length of the tuple, python language provides us with the len() function.

 

Example

Input

tup = (22, 3, 45, 4, 2, 56, 890, 1)
print(len(tup))

 

Output

8

 

Tuples in a loop

We can loop through the tuples using the 'for' or 'while' loop.

 

Example

Input:

tup1 = (1, 2, 3)
n = 3 
for i in range(int(n)):
print(tup1)

 

Output

(1, 2, 3)
(1, 2, 3)
(1, 2, 3)

Inbuilt Functions of Python

type()

Tuples are defined as objects with the data type 'tuple':

 

Example

Input:

tup1 = ("Coding", "Ninjas")
print(type(tup1))

 

Output

<class 'tuple'>

 

cmp()

It compares the elements of both the tuples.

 

Example:

Input:

tup1 = ('Coding', 'Ninjas')
tup2 = ('Hello', 1)

if (cmp(tup1, tup2) != 0):
print('Not same')
else:
print('Same')

 

Output

Not same

 

max() 

It returns the item with the max value in the tuple.

 

Example

Input:

tup1 = ('Coding', 'Ninjas')
tup2 = ('Hello', 1)
print ( str(max(tup1)))

 

Output

Ninjas 

 

min()

It returns the item with the max value in the tuple.

 

Example

Input:

tup1 = ('Coding', 'Ninjas')
tup2 = ('Hello', 1)
print ( str(min(tup2)))

 

Output

1

FAQ'S

1). What do you mean by a tuple?

A tuple is a built-in data type that stores multiple items in a single variable. Tuples show the immutable property, which means they can't be changed or modified.

 

2). How are lists different from tuples?

Both lists and tuples are the collection data types of the python language, but the main difference is that tuples are immutable and lists are mutable.

 

3). What do you mean by immutability?

Immutable means tuples can't be changed or modified.

 

4). Name the different built-in data types in Python language.

There are four inbuilt data types in Python language, namely:

• Lists
• Tuples
• Dictionaries
• Sets
