Q: Python Tuple

1 Answer

Dec 12, 2019
Python Tuple is used to store the sequence of immutable python objects. Tuple is similar to lists since the value of the items stored in the list can be changed whereas the tuple is immutable and the value of the items stored in the tuple can not be changed.

A tuple can be written as the collection of comma-separated values enclosed with the small brackets. A tuple can be defined as follows.

T1 = (101, "Ayush", 22)  

T2 = ("Apple", "Banana", "Orange")   

Example

tuple1 = (10, 20, 30, 40, 50, 60)  

print(tuple1)  

count = 0  

for i in tuple1:  

    print("tuple1[%d] = %d"%(count, i));  

Output:

(10, 20, 30, 40, 50, 60)

tuple1[0] = 10

tuple1[0] = 20

tuple1[0] = 30

tuple1[0] = 40

tuple1[0] = 50

tuple1[0] = 60

Example 2

tuple1 = tuple(input("Enter the tuple elements ..."))  

print(tuple1)  

count = 0  

for i in tuple1:  

    print("tuple1[%d] = %s"%(count, i));  

Output:

Enter the tuple elements ...12345

('1', '2', '3', '4', '5')

tuple1[0] = 1

tuple1[0] = 2

tuple1[0] = 3

tuple1[0] = 4

tuple1[0] = 5

However, if we try to reassign the items of a tuple, we would get an error as the tuple object doesn't support the item assignment.

An empty tuple can be written as follows.

T3 = ()  

The tuple having a single value must include a comma as given below.

T4 = (90,)   

A tuple is indexed in the same way as the lists. The items in the tuple can be accessed by using their specific index value.

We will see all these aspects of tuple in this section of the tutorial.

Tuple indexing and splitting

The indexing and slicing in tuple are similar to lists. The indexing in the tuple starts from 0 and goes to length(tuple) - 1.

The items in the tuple can be accessed by using the slice operator. Python also allows us to use the colon operator to access multiple items in the tuple.
