Python | Data Structure Or Data Type (Tuple)

Data Type Of Python

 In this session we will see last data type of python which is Tuple.

5) Tuple:- Tuple is a ordered collection of immutable datatype, tuples are quite similar to lists but difference is list are mutable where as tuple are immutable.

• Empty tuple:- 
  t = () or tuple()
  
  
• Tuple with single element:-
  t = (10,)
  
  
• Tuple with multiple element:-
  t1 = ( 10, 20, 30, 'Hello' )
  
  
• Nested tuple:- 
  t1 = ( 10, 20, 30, 'Hello' )
  p = t2, 30, 40, 50
  print(p) => ((10, 20, 30, 'Hello'), 30, 40, 50)
  
  

Methods of Tuple:- 

1. count(value):- It return the count of value if the value is present in the tuple else it return 0.
   For example:-
   t = (10, 20, 30, 'Hello')
   t.count(10) => 1 
   t.count(50) => 0
   
   
2. index(value,start,end):- It return the index number if the value is present in the tuple, otherwise it raised value error.
   For example:-
   t = (10, 20, 30, 'Hello')
   t.index(10) => 0
   It return the index number of value 10.
