python之路——29

学习内容

1.configparser 处理配置文件的模块
2.login 登陆
  log 日志——记录用户行为或者代码的执行过程
  logging——1.“一键”控制
             2.排错时候打印细节
             3.严重的错误记录下来
             4.一些用户行为，有没有错都要记录
3.log对象配置
    1.程序充分解耦
    2.程序高可定制
4.logging
    有5种级别的日志记录模式
    两种配置方式：basicconfig log对象

1.configparper logging模块

# configparser 模块
'''
import configparser
config = configparser.ConfigParser()
config['DEFAULT'] = {'one': '1'}
config['address'] = {'two':'2'}
with open('example.ini','w') as f:
    config.write(f)

config.read('example.ini')
print(config.sections())
print(config['address']['one'])
for key in config['address']:
    print(key)
print(config.items('address'))
'''
# logging 模块
'''
import logging
logging.debug('1')
logging.info('2')
logging.warning('3')
logging.error('4')
logging.critical('5')

import logging
logger = logging.getLogger()
fh = logging.FileHandler('log.log',encoding='utf-8')
sh = logging.StreamHandler()
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
fh.setFormatter(formatter)
# sh.setFormatter(formatter)
logger.addHandler(fh)
logger.addHandler(sh)
logging.debug('一')
logging.info('二')
logging.warning('三')
logging.error('四')
logging.critical('五')

2.1234组成无重复的三位数

def comb():
    count = 0
    for i in range(1,5):
        for j in range(1,5):
            for k in range(1,5):
                if i == j or i == k or j == k:
                    continue
                count += 1
                yield str(i)+str(j)+str(k), count

for i,j in comb():
    print(i,j)

3.实例化10各类，找出年纪最大的

class Person:
    def __init__(self,name,age):
        self.name = name
        self.age = age
l = []
for i in range(10):
    l.append(Person('alex'+str(i),i+10))

ret = max(l,key=lambda obj:obj.age)
print(ret.age)

4.CS

class Person:
    def __init__(self,name, blood, weapon, gender):
        self.name = name
        self.blood = blood
        self.weapon = weapon
        self.gender = gender

    def attack(self, obj):
        obj.blood -= self.weapon

class Police(Person):
    def __init__(self,name,blood,weapon,gender,role):
        self.role = role
        super().__init__(name,blood,weapon,gender)

class Terrorist(Person):
    def __init__(self, name, blood, weapon, gender, role):
        self.role = role
        super().__init__(name, blood, weapon, gender)



a = Police('alex',100,1,'man','police')
b = Terrorist('alex',100,10,'man','police')
a.attack(b)
print(b.blood)
