Python中如何导入类示例详解

class User():
 '''账号信息'''

 def __init__(self, name, pwd):
  '''初始化'''
  self.name = name
  self.pwd = pwd
  # 登陆次数
  self.login_count = 0

 def print_login_count(self):
  '''打印登陆次数'''
  print('登陆次数=' + str(self.login_count))

 def update_login_count(self, num):
  '''更新登陆次数'''
  self.login_count = num

 def valid(self):
  '''是否验证通过'''
  print(self.name + ' 验证通过')

from User import User


deniro = User('deniro', '1')
print('账号名：' + deniro.name)

class User():
 '''账号信息'''

 def __init__(self, name, pwd):
  '''初始化'''
  self.name = name
  self.pwd = pwd
  # 登陆次数
  self.login_count = 0
  # 拥有的权限
  self.privileges = Privilege(['修改某某账号密码', '禁用某某账号'])

 def print_privileges(self):
  '''打印拥有的权限'''
  print(self.privileges.contents)

...






class Privilege():
 '''权限'''

 def __init__(self, contents):
  self.contents = contents

# 导入一个类
from User import User


deniro = User('deniro', '1')
print('拥有的权限：' + str(deniro.privileges.contents))

from User import User,Privilege

p=Privilege(["删除账号权限"])
print('权限内容：'+str(p.contents))

import User

...

p=User.Privilege(["删除账号权限"])
...

from User import *
