信用卡取现流程需知details_tip

信用卡取现需知-》》
①信用卡默认取现额度为信用卡总额度的50%(此系统默认取现额度为7500)
②信用卡进行消费时(未取现)，取现额度不会变化
③信用卡额度低于取现额度时，可取现金额以当前额度为准(可取现金额=当前额度*0.95）
④取现额度只有两种状况会发生变化，一种进行取现，第二是对信用卡额度进行调整
⑤每次取现扣除5%的手续费

定义三种日志输出格式 开始

standard_format = '[%(asctime)s][%(threadName)s:%(thread)d][task_id:%(name)s][%(filename)s:%(lineno)d]' \
'[%(levelname)s][%(message)s]'

simple_format = '[%(levelname)s][%(asctime)s][%(filename)s:%(lineno)d]%(message)s'

id_simple_format = '[%(levelname)s][%(asctime)s] %(message)s'
