md5

实例

import hashlib

# 1. 创建一个MD5对象
obj = hashlib.md5(b"flkjsdalkfjklasdjfklasjkflasdjklfasdjflkadsj") # 加盐

# 2. 把要加密的内容给md5
obj.update("alex".encode("utf-8")) # 必须是字节

# 3. 获取密文
val = obj.hexdigest()   # 534b44a19bf18d20b71ecc4eb77c572f aa7aa5ec13222b27f76a094207c5ac75
print(val)

def my_md5(val):
    obj = hashlib.md5(b"flkjsdalkfjklasdjfklasjkflasdjklfasdjflkadsj")
    obj.update(val.encode("utf-8"))
    val = obj.hexdigest()
    return val

注册的时候. 用md5进行加密. 存储的是加密后的密文
username = input("请输入用户名")
password = input("请输入密码")
# cun = my_md5(password)
# print(cun) # alex 26adff81aa6778d26999b95ddc0e50b2
if username == "alex" and my_md5(password) == "26adff81aa6778d26999b95ddc0e50b2":
    print("登录成功")
else:
    print("登录失败")

单日志

import logging
import traceback

logging.basicConfig(filename='app.log',
                    format='%(asctime)s - %(name)s - %(levelname)s - %(module)s: %(message)s',
                    datefmt='%Y-%m-%d %H:%M:%S',
                    level=40)    # level 设置级别. 当你的信息的级别>=level的时候才会写入日志文件, 默认30

for i in range(20):
    try:
        if i % 3 == 0:
            raise FileNotFoundError("我是FileNotFountException")
        elif i % 3 == 1:
            raise StopIteration()
        elif i % 3 == 2:
            raise KeyError()

    except FileNotFoundError as e:
        val = traceback.format_exc()
        logging.error(val)
    except StopIteration as e:
        val = traceback.format_exc()
        logging.error(val)
    except KeyError as e:
        val = traceback.format_exc()
        logging.error(val)
    except Exception as e:
        val = traceback.format_exc()
        logging.error(val)

多日志处理

# 创建⼀个操作⽇志的对象logger（依赖FileHandler）
file_handler = logging.FileHandler('l1.log', 'a', encoding='utf-8')
# 设置日志文件内容的格式
file_handler.setFormatter(logging.Formatter(fmt="%(asctime)s - %(name)s - %(levelname)s -%(module)s: %(message)s"))
logger1 = logging.Logger('A', level=40)
logger1.addHandler(file_handler)
# 记录日志
logger1.error('我是A系统')



# 再创建⼀个操作⽇志的对象logger（依赖FileHandler）
file_handler2 = logging.FileHandler('l2.log', 'a', encoding='utf-8')
file_handler2.setFormatter(logging.Formatter(fmt="%(asctime)s - %(name)s -%(levelname)s -%(module)s: %(message)s"))
logger2 = logging.Logger('B', level=40)
logger2.addHandler(file_handler2)
# 记录日志
logger2.error('我是B系统')
