Finding the Number of Elements in a List (List Length) in Python

In Python, determining the number of elements in a list, also known as the list length, is a common operation. To achieve this, we can utilize the len() function.

For instance, consider the list items = ["apple", "orange", "banana"]. To find the number of elements in this list:

items_length = len(items)
print(items_length)

This will print 3, which represents the count of elements in the list.

The len() function is not limited to lists. It can be used with various other types, including strings, tuples, sets, and dictionaries. For example:

>>>> len([1, 2, 3])  # List
3
>>>> len("Hello")  # String
5
>>>> len({1, 2, 3})  # Set
3
>>>> len({"apple": "fruit", "banana": "fruit"})  # Dictionary
