连写两天博客实在是！！！愚蠢的人类啊
1.双层（多层）装饰器：装饰器就是将原函数装饰成另外一个函数，既然又成为了函数，当然可以再被装饰，理解这个理念就可以了，层数关系是由下到上一层层被包装的！如果还不理解，去百度吧！北方不想给愚蠢的人类进行过多的解释（其实是语文学的不好的缘故...
）
2.模块：不要起一个跟内置模块重名的文件名！！！
3.生成器：yield
4.日志模块：
1 #!/usr/bin/env python 2 import logging 3 logger= logging.getLogger('北方姆Q') 4 logger.setLevel(logging.INFO) 5 6 ch = logging.StreamHandler() 7 ch.setLevel(logging.ERROR) 8 9 fh = logging.FileHandler('log.txt') 10 fh.setLevel(logging.DEBUG) 11 12 formatter1 = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s') 13 formatter2 = logging.Formatter('%(asctime)s - %(lineno)d - %(process)d- %(levelname)s - %(message)s') 14 15 ch.setFormatter(formatter2) 16 fh.setFormatter(formatter1) 17 18 logger.addHandler(ch) 19 logger.addHandler(fh) 20 21 logger.debug('DEBUG!') 22 logger.info('INFO!') 23 logger.warning('WARNING!') 24 logger.error('ERROR!') 25 logger.critical('CRITICAL!')

5.时间模块：
1 #!/usr/bin/env python 2 import time 3 print(time.time()) #从1970-1-1起到现在的时间戳 4 print(time.ctime()) #当前日期 5 print(time.ctime(time.time()-86400)) #将时间戳转化成字符串 6 print(time.gmtime()) #将当前时间戳转化成struct_time格式 7 print(time.localtime()) #将本地时间戳转化成struct_time格式 8 print(time.mktime(time.localtime())) #与ocaltime()相反 9 #time.sleep(3) #阻塞时间 10 print(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime())) #将struct_time格式转换成指定格式 11 print(time.strptime('2012-12-12', '%Y-%m-%d'))
