List Length
When working with large or complex lists, knowing how many elements they contain is often useful. Python provides the len() function, which returns the total number of items in a list.
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.
cities_list = ["Tokyo", "New York", "Sydney", "Berlin", ["Paris", "France"]] list_length = len(cities_list) print(list_length)
