Last occurrence of some element in a list in Python

In this article, we are going to see different ways to find the last occurrence of an element in a list.

Let's see how to find the last occurrence of an element by reversing the given list. Follow the below steps to write the code.

Initialize the list.
Reverse the list using reverse method.
Find the index of the element using index method.
The actual index of the element is len(list) - index - 1.
Print the final index.

Example

Let's see the code.

# initializing the list
words = ['eat', 'sleep', 'drink', 'sleep', 'drink', 'sleep', 'go', 'come']
element = 'sleep'

# reversing the list
words.reverse()

# finding the index of element
index = words.index(element)

# printing the final index
print(len(words) - index - 1)

If you run the above code, then you will get the following result.

Output

Another way is to find all the indexes and getting the max from it.

Example

Let's see the code.

# initializing the list
words = ['eat', 'sleep', 'drink', 'sleep', 'drink', 'sleep', 'go', 'come']
element = 'sleep'

# finding the last occurrence
final_index = max(index for index, item in enumerate(words) if item == element)

# printing the index
print(final_index)

If you run the above code, then you will get the following result.
