In python Tuple is used to store the sequence of immutable Python objects.
It is similar to lists since the value of the items stored in the list can be changed.
If the tuple is immutable then the value of the items stored in the tuple cannot be changed.
It can be written as the collection of comma-separated (,) values enclosed with the small () brackets.
The parentheses are optional but it is good practice to use.
A tuple is indexed in the same way as the lists then items in the tuples can be accessed by using their specific index value.
Using negative indexing tuple element can also access then index of -1 denotes the rightmost element and -2 to the second last item and so on.
The tuple items cannot be deleted by using the delkeyword as tuples are immutable, unlike lists.
We can use del keyword with the tuple name, to delete an entire tuple.
Concatenation (+), Membership (in), repetition (*) are the operators works in the same way as they work with the list.
Using tuple instead of list gives us a clear idea that tuple data is constant and must not be changed.
It can simulate a dictionary without keys and it can be used a dictionary which is consider the following nested structure.

tup1 = ("Wikitechy") 
        print(type(tup1))  
        #Creating a tuple with single element   

tup2 = ("Wikitechy",)  

print(type(tup2))
