python入门五

1.多继承

class A(object):    
       def fly(self):        
          print 'fly'
class B(object):   
        @staticmethod    
        def sleep():      
             print 'sleep'
class C(A, B):    
       pass
p = C()
p.fly()

这个里和java不同的是java是单继承，python是多重继成

2.日志打印

import logginglogging.basicConfig(level=logging.INFO)class A(object):    def fly(self):        logging.info('fly')class B(object):    @staticmethod    def sleep():        print 'sleep'class C(A, B):    passp = C()p.fly()

3.读取本地文件

try:    f = open('C:\\Users\\Administrator\Desktop\\remind.txt', 'r')   
print f.read().decode("gbk")
finally:    
f.close()

写文件

try:    f = open('C:\\Users\\Administrator\Desktop\\remind.txt', 'w')    
print f.write('haha我是都比')
finally:    f.close()
