len is a function to get the length of a collection. It works by calling an object's len method. something attributes are special and usually more than meets the eye, and generally should not be.
From the docs len(s) Return the length (the number of items) of an object. The argument may be a sequence (such as a string, bytes, tuple, list, or range) or a collection (such as a dictionary,.
Understanding the Context
I found two ways to determine how many elements are in a variable I always get the same values for len () and size (). Is there a difference? Could size () have come with an imported library (like...
For such simple case, for ind in range(len(sequence)) is generally considered an anti-pattern. The are cases when it's useful to have the index around, though, such as when you need to.
42 <class 'main.INT'> 42 <type 'int'> How can I handle it so len returns an INT instance? Answers suggest that the only solution is overriding len This is my alternative implementation. It doesn't.
Python: TypeError: object of type 'NoneType' has no len() The assert statement is throwing this error, what am I doing wrong?

Explains how to use len() to determine the size of a numpy array in Python, with examples and discussions on its functionality.
You can also do df[df['Surname'].apply(len) > 9] by the way which evaluates each string present in the series and returns True if the condition is satisfied.
Part of the reason for the len function vs using .len() or .len() is that python was intended to be a language that is easy to learn. For a beginner programmer, understanding that you use.
