我在导入时有一个简单的错误 但是如何解决呢?;)) 我是菜鸟,正在测试任务
其中一个条件是将父类与子类分开! 也就是说,一切都因其位置[classes_1.py,classes_2.py]
而好主要:
n10_12.py
from classes_1 import User
from classes_2 import Privileges, Admin
admin_33 = Admin('mike', 'logsdale', 'africa', 'customer')
admin_33.privilege.show_privileges()
admin_33.descibe_user()
分类两个文件:
1)
classes_1.py
class User():
def __init__(self, first_name, last_name, location='', field=''):
self.first_name = first_name
self.last_name = last_name
self.location = location
self.field = field
self.full_name = self.first_name.title() + ' ' + self.last_name.title()
self.login_attemts = 0
def descibe_user(self):
print('\nFull name: ' + self.full_name +
'\nLocation: ' + self.location.title() +
'\nField: ' + self.field.title() + '\n'
)
def greet_user(self):
print('Hello, ' + self.full_name)
def read_login_attemts(self):
print('In this time login attempts are ' + str(self.login_attemts))
def increment_login_attempts(self):
self.login_attemts += 1
def reset_login_attempts(self):
self.login_attemts = 0
2)
classes_2.py
class Privileges():
def __init__(self):
self.privileges = [
'access to add msg',
'access to delete users',
'access to ban users',
]
def show_privileges(self):
print('Hi Admin, your privileges is: ')
for kk in self.privileges:
print('\n- ' + kk.lower())
class Admin(User):
def __init__(self, first_name, last_name, location='', field=''):
super().__init__(first_name, last_name, location, field)
self.privilege = Privileges()
跟踪:
python n10_12.py
回溯(最近通话最近一次):
文件“ n10_12.py”,第2行,在 从classes_2导入权限,管理员
文件.. \ classes_2.py”,第28行,在 类别Admin(User):
NameError:未定义名称“用户”
答案 0 :(得分:4)
您需要在class_2.py中导入User:
