Python Tuple Methods| count() and index() in Python Tuples

Pre-requisite : All about Python Tuples

count() method in Python Tuple

count() method in Python Tuple can be used to count the number of occurrences of a given element in a tuple.

The count() method returns an integer value denoting how many times a particular element is found in a tuple.

Syntax

tuple.count(item)

tup = (10, 13, 12, 14, 15, 20, 15)
print(tup.count(15))

Counting an inner tuple inside main tuple

tup = (10, 15, (10, 20), 40, (10, 20), (10, 20, 30), (10, 20))
print(tup.count((10, 20)))

index() method in Python Tuple

index() method in Python Tuple can be used to find the first occurrence of a given element in the given tuple.

The index() method by default, returns an integer, denoting the first occurrence of the given element in that tuple.

Please note that, integer is returned as per 0 based indexing.

Syntax

tuple.index(item)

item: element whose index is required.

l = (1, 3, 5, 2, 8, 3)
print(l.index(2)) # returns 3
print(l.index(8)) # returns 4
print(l.index(3)) # returns 1 ignoring the further occurrences

O/P

3
4
1

If we try to find the index of the element which does not exists in the given tuple, then, we get

ValueError : item is not in tuple

Let’s modify the above code (a bit)

l = (1, 3, 5, 2, 8, 3)
print(l.index(10))

O/P

Traceback (most recent call last):
File “”, line 2, in
ValueError: 10 is not in tuple

That’s all here.
