Why doesn't deepcopy work?

Question

Python

command = tools.get_attr_recursive(scripts, command_class_name) 
# command.name по умолчанию пуст
# print(command.name)
# ""
self.commands[command_name] = copy.deepcopy(command)
self.commands[command_name].name = command_name
print(command.name, self.commands[command_name].name)
# command.name == self.commands[command_name].name
# True

Answer 1

short topic like this

import copy


class Command(object):
    name = ""


cmd = Command
cmd2 = copy.deepcopy(Command)
assert cmd == cmd2

copying really does not give anything, because as it is written here copy and deepcopy are copying objects
in our case, there really are no instances
what you want to do is to create a class with similar behavior but a little different
there is an option to inherit and redefine the necessary parts,
or you can assemble the class manually by reusing guts from the original class

class Command(object):
    name = ""

cmd = Command
cmd3 = type('NewCommand', Command.__bases__, dict(Command.__dict__))
assert cmd == cmd3  # AssertionError
