```python
# 1. use dataclass at python3.7+, recommended
from dataclasses import dataclass


@dataclass
class Data(object):
a: int
b: int
c: int
d: int


data = Data(1, 2, 3, 4)
print(data)
# Data(a=1, b=2, c=3, d=4)
print(data.a, data.b, data.c, data.d)
# 1 2 3 4

# 2. Use namedtuple

from typing import NamedTuple


class Data(NamedTuple):
a: int
b: int
c: int
d: int


data = Data(1, 2, 3, 4)
print(data)
# Data(a=1, b=2, c=3, d=4)
print(data.a, data.b, data.c, data.d)
# 1 2 3 4

# 3. Use __dict__ without __slots__


class Data(object):

def __init__(self, **kwargs):
super().__init__()
self.__dict__.update(kwargs)


data = Data(a=1, b=2, c=3, d=4)
print(data.a, data.b, data.c, data.d)
# 1 2 3 4

# 4. Use setattr with __slots__


class Data(object):
__slots__ = ('a', 'b', 'c', 'd')

def __init__(self, **kwargs):
super().__init__()
for k, v in kwargs.items():
setattr(self, k, v)


data = Data(a=1, b=2, c=3, d=4)
print(data.a, data.b, data.c, data.d)
# 1 2 3 4

```
