How to Find the Index of an Element in a List or Tuple in Python

Lists are pretty much widely used throughout every project that you can think of. Tuples, on the other hand, are not that common, but both of them have something in common that you can use right away.

You can use the same method for both of them to find indexes of certain elements.

All you have to do is use the index() method.

Let’s see this in action.

Let us take an array of tuples and see this method being used:

	books_tuple = ('Atomic habits', 'Ego is the enemy', 'Outliers', 'Mastery')
	print(books_tuple.index('Mastery')) # 3

You can use the same for lists as well:

	books_list = ['Atomic habits', 'Ego is the enemy', 'Outliers', 'Mastery']
	print(books_list.index('Mastery')) # 3

That’s basically it for this article.
