Python - Access to all attributes in a dictionnary

I would like to access to attribute of objects in a dictionary in order to find the object with the maximum value on this argument. For example i have this:

class MyClass:
    def __init__(self,name,value):
        self.name=name
        self.value=value


Dict=dict()

object_1 = MyClass("object_1",1)
Dict[object_1.name]=object_1

object_2 = MyClass("object_2",5)
Dict[object_2.name]=object_2

and i would like to do something like:

max(dict.value)

But i can't figure how to acces the attribute of all the object. Can you help me please?

Simple genereator fed to max function

max(obj.value for obj in Dict.values())

If you want just the max value:

maxval = max(x.value for x in Dict.values())

If you want the key (name) of this object:

name = max(Dict.keys(), key=lambda x: Dict[x.value)
