How to sort a list of objects based on an attribute of the objects?
You can use the
sort method of a list and pass in a
key argument, which is a function that takes an object and returns the value on which you want to sort the list. For example, if you have a list of objects
my_list and each object has an attribute
my_attribute, you can sort the list based on that attribute like this:
my_list.sort(key=lambda x: x.my_attribute)
This will sort the list in ascending order based on the value of
my_attribute. To sort in descending order, you can pass in the
my_list.sort(key=lambda x: x.my_attribute, reverse=True)
Alternatively, you can use the
sorted() function in python that takes in the list and a key function and returns a sorted list.
sorted_list = sorted(my_list, key=lambda x: x.my_attribute)
