bookFinding Elements in a Tuple

The index() method in Python is used to find the first occurrence of a specified element in a tuple. It returns the index of the element, which is helpful when you need to locate the position of specific data.

The method returns the first index where the element is found. If the element is not present in the tuple, a ValueError is raised.


              
1234567

            
# Tuple of movies
movies = ("Inception", "Interstellar", "Tenet", "Dunkirk", "Memento")

# Find the index of "Tenet"
tenet_index = movies.index("Tenet")

print(f"'Tenet' is at index {tenet_index}.")
copy

The result, 2, indicates that "Tenet" is the third element (since indexing starts at 0).
