如何在Python中查看/保存对象的所有行？

obj = SomeObject()
attributes = dir(obj)
for attr in attributes:
    print(attr)

obj = SomeObject()
attributes = vars(obj)
for attr, value in attributes.items():
    print(attr, value)

import inspect

obj = SomeObject()
members = inspect.getmembers(obj)
for member in members:
    print(member)

import pickle

obj = SomeObject()
with open('object.pickle', 'wb') as f:
    pickle.dump(obj, f)
    
with open('object.pickle', 'rb') as f:
    obj = pickle.load(f)
