Why can't I use __setitem__?

[andreyu-git]

Hello!

Tell me why it doesn't work, what is the error?

class User(object):
    def __init__(self, user):
        for k, v in user.items():
            #self.__dict__[k] = v
            self.__dict__.__setitem__(k, v)
            


p = User({'age':'25','name':'Tom'})


print(p.name)

TypeError:

ESP32

Thanks!

It's a different implementation. Some double under methods are missing or implemented in C.

self.__dict__.__setitem__(k, v) feels very wrong. Don't do this.

@andreyugit Can you use setattr instead?

e.g. the following works:

class User(object):
    def __init__(self, user):
        for k, v in user.items():
            setattr(self, k, v)
            
p = User({'age':'25','name':'Tom'})

print(p.name)
