The ProblemJump To Solution

How do I determine the number of elements in a list in Python?

The Solution

You can do this using Python’s built-in len() function. For example:

Click to Copy
products = ["Apples", "Oranges", "Pears"] product_count = len(products) print(product_count) # will output "3"

The len() function works by calling the provided object’s __len__() method. The len() function works with other iterable data types in Python as well, such as strings, tuples, and sets.
