How to Get the Length of a Python List?

To get the length/size of a list in Python, we can simply use the built-in len() function like so:

list = []
list.append('foo')
list.append('bar')
list.append('baz')

print(len(list)) # output: 3

The len() function takes an object as an argument and returns the total number of items (i.e. the length of the object). It has the following syntax:

len(object)

Since a list in Python is an object, the len() function works for it and returns the total number of items in the list.
