How to sort a list of objects based on an attribute of the objects?

Question

I\'ve got a list of Python objects that I\'d like to sort by an attribute of the objects themselves. The list looks like:

>>> ut
[,         


        

Answer 1

If the attribute you want to sort by is a property, then you can avoid importing operator.attrgetter and use the property's fget method instead.

For example, for a class Circle with a property radius we could sort a list of circles by radii as follows:

result = sorted(circles, key=Circle.radius.fget)

This is not the most well-known feature but often saves me a line with the import.
