import pickle
accounts = {
1000:{
"name":"alex li",
"email":"lijie@126.com",
"passwd":"adc123",
"balance":15000,
"phone":13651054608,
"bank_acc":{
"ICBC":2321434,
"CBC":413432,
"ABC":76568,
}
},
1001: {
"name": "chen li",
"email": "wangxiao@126.com",
"passwd": "adcewrf23",
"balance": 15000,
"phone": 13651054608,
"bank_acc": {
"ICBC": 23214434,
"CBC": 4132432,
"ABC": 7655668,
}
},
}
f = open("account.db","wb")#
f.write(pickle.dumps(accounts))
f.close()
2：
import pickle
acc_file_name = "account.db"
account_file = open(acc_file_name,"rb")
account_dic = pickle.loads(account_file.read())#加载字典数据
account_file.close()
account_dic[1000]["balance"] -=500
f = open(acc_file_name,"wb")
f.write(pickle.dumps(account_dic))
f.close()
print(account_dic)
#扣完钱在写入文件
3：
import pickle
f = open("account.db","rb")
account_db = pickle.loads(f.read())
print(account_db)
其中pickle模块与json大致相同
