bookList Length

When dealing with a sizable list, you might want to know the number of items it contains. You can determine this using the len() function, which returns the count of elements in the list. Let's dive into how it operates!

Note

A nested list is considered a single item. The len() function doesn't count the individual items inside a nested list as separate items of the main list.

x = ['hello', 'Alisa', 5, 23, 'green', 54, 'car', 7]
print(len(x))
copy

Task
