Finding Elements in a Tuple: Using the index() Method for Lookup
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.
tuple_name.index(value)
The method returns the first index where the element is found.
If the element is not present in the tuple, a ValueError
is raised.
# 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}.")
The result, 2
, indicates that "Tenet"
is the third element (since indexing starts at 0
).
