How to get the number of elements in a list (length of a list) in Python?

You can get the number of elements in a list (the length of a list) in Python using the built-in len() function. Here's how to use it:

my_list = [1, 2, 3, 4, 5] # Get the length of the list length = len(my_list) print("The length of the list is:", length)

Output:

The length of the list is: 5

The len() function takes the list as an argument and returns the number of elements in that list. This method works for lists of any data type and is a common way to determine the size of a list in Python.
