Len is a function to get the length of a collection. It works by calling an object's __len__ method. I found two ways to determine how many elements are in a variable… i always get the same values for len () and size (). Like others, i can't think of many use cases for for idx in range(len(x)):. The len() function will use the __len__ method if present to query your object for it's length. The normal api people expect to use is the len() method, using a.len attribute. So a list object does not have a simple length attribute len but rather the magic __len__(). Could size () have come with an.

Len() returns the number of items (the length) of a list object (also works for dictionary, string, tuple or range objects). I know that python has a len() function that is used to determine the size of a string, but why is it not a method of the string object? Why is it preferred to use the function len() on a list rather than its attribute? For a normal list both are equivalent, but length_hint makes it possible to get the length of a list. The only one that really pops to mind is if you need to remove elements from x over the course of the.
