What must I do to use my objects of a custom type as keys in a Python dictionary (where I don’t want the “object id” to act as the key) , e.g.
class MyThing:
def __init__(self,name,location,length):
self.name = name
self.location = location
self.length = length
I’d want to use MyThing’s as keys that are considered the same if name and location are the same.
From C#/Java I’m used to having to override and provide an equals and hashcode method, and promise not to mutate anything the hashcode depends on.
What must I do in Python to accomplish this ? Should I even ?
(In a simple case, like here, perhaps it’d be better to just place a (name,location) tuple as key – but consider I’d want the key to be an object)
