我将分享我的解决方案。我需要一种方法,在程序崩溃或由于某些原因停止时保存属性,以便它知道应该从输入列表的哪个位置恢复。基于@GabrielStaples的答案:
import pickle, json
class ScanSession:
def __init__(self, input_file: str = None, output_file: str = None,
total_viable_wallets: int = 0, total: float = 0,
report_dict: dict = {}, wallet_addresses: list = [],
token_map: list = [], token_map_file: str = 'data/token.maps.json',
current_batch: int = 0):
self.initialized = time.time()
self.input_file = input_file
self.output_file = output_file
self.total_viable_wallets = total_viable_wallets
self.total = total
self.report_dict = report_dict
self.wallet_addresses = wallet_addresses
self.token_map = token_map
self.token_map_file = token_map_file
self.current_batch = current_batch
@property
def __dict__(self):
"""
Obtain the string representation of `Point`, so that just typing
the instance name of an object of this type will call this method
and obtain this string, just like `namedtuple` already does!
"""
return {'initialized': self.initialized, 'input_file': self.input_file,
'output_file': self.output_file, 'total_viable_wallets': self.total_viable_wallets,
'total': self.total, 'report_dict': self.report_dict,
'wallet_addresses': self.wallet_addresses, 'token_map': self.token_map,
'token_map_file':self.token_map_file, 'current_batch': self.current_batch
}
def load_session(self, session_file):
with open(session_file, 'r') as f:
_session = json.loads(json.dumps(f.read()))
_session = dict(_session)
for key, value in _session.items():
setattr(self, key, value)
def dump_session(self, session_file):
with open(session_file, 'w') as f:
json.dump(self.__dict__, fp=f)
使用它:
session = ScanSession()
session.total += 1
session.__dict__
{'initialized': 1670801774.8050613, 'input_file': None, 'output_file': None, 'total_viable_wallets': 0, 'total': 10, 'report_dict': {}, 'wallet_addresses': [], 'token_map': [], 'token_map_file': 'data/token.maps.json', 'current_batch': 0}
pickle.dumps(session)

namedtuple
不同的是,似乎您无需能够通过索引引用属性,即p[0]
和p[1]
将是分别引用x
和y
的替代方式,对吗? - martineau
