二、shelve模块
是一个简单的k，v将内存数据通过文件持久化的模块，可持久化任何pickle可支持的python数据格式。
1 import shelve 2 3 d = shelve.open(‘shelve_test‘) #打开一个文件 4 5 class Test(object): 6 def __init__(self,n): 7 self.n = n 8 9 10 t = Test(123) 11 t2 = Test(123334) 12 13 name = ["alex","rain","test"] 14 d["test"] = name #持久化列表 15 d["t1"] = t #持久化类 16 d["t2"] = t2 17 18 d.close()
三、loggin模块
用于日志管理，将日志进行记录、收集、输出、打印等。
import logging ‘‘‘ logging.warning(‘attempted wrong password‘) logging.critical(‘server is down‘) logging.basicConfig(filename=‘example.log‘,level=logging.INFO,format=‘%m/%d/%Y %I:%M:%S %p‘) logging.debug(‘This message should go to the log file‘) logging.info(‘So should this‘) logging.warning(‘And this,too‘) ‘‘‘ logging.basicConfig(filename=‘example.log‘,level=logging.INFO,format=‘%(asctime)s %(message)s‘, datefmt=‘%m/%d/%Y %I:%M:%S %p‘) logging.warning(‘is when this event was logged.‘)
四、类
1、继承
1 class SchoolMember(object): 2 member_nums = 0 3 def __init__(self,name,age,sex): 4 self.name = name 5 self.age = age 6 self.sex = sex 7 self.enroll() 8 def enroll(self): 9 print(‘SchoolMember [%s] is enrolled!‘ % self.name) 10 SchoolMember.member_nums += 1 11 print(‘The [%s] school member [%s] is enrolled!‘ % (self.member_nums,self.name)) 12 def tell(self): 13 print(‘Hello,my name is %s‘ %self.name) 14 15 class Teacher(SchoolMember): 16 def __init__(self,name,age,sex,course,salary): 17 super(Teacher,self).__init__(name,age,sex) #继承 18 self.course = course 19 self.salary = salary 20 def teaching(self): 21 print(‘Teacher [%s] is teaching [%s]‘%(self.name,self.course)) 22 23 class Student(SchoolMember): 24 def __init__(self,name,age,sex,course,tuition): 25 super(Student,self).__init__(name,age,sex) 26 self.course = course 27 self.tuition = tuition 28 def pay_tuition(self): 29 print(‘NND,student [%s] pay tuition [%s]‘ %(self.name,self.tuition)) 30 31 t1 = Teacher(‘Jef‘,22,‘F‘,‘Py‘,1000) 32 t2 = Teacher(‘Jia‘,3,‘F‘,‘JS‘,2000) 33 34 s1 = Student(‘Jingjing‘,27,‘M‘,‘Travel‘,10000) 35 s2 = Student(‘Doudou‘,5,‘N/A‘,‘Eat‘,100) 36 37 t1.tell() 38 t1.teaching() 39 s1.tell() 40 s1.pay_tuition()
