1、带参数的装饰器执行过程的跳转很晕，设置了断点一步一步执行，仍不清楚执行步骤

 1 #本地验证
 2 user,passwd = "abc","123"
 3
 4 def auth(auth_type):
 5     print("auth func:",auth_type)
 6     def outer_wrapper(func):
 7         def wrapper(*args,**kwargs):
 8             print("wrapper func args:",*args,**kwargs)
 9             username = input("Username:").strip()
10             password = input("Password:").strip()
11             if auth_type == "local":
12                 if user == username and passwd == password:
13                     print("\033[32mUser has passed authentication\033[0m")
14                     res = func(*args,**kwargs)
15                     print("--after authentication")
16                     return res
17                 else:
18                     exit("Invalid username or password")
19             elif auth_type == "ldap":
20                 pass
21         return wrapper
22     return outer_wrapper
23
24 def index():
25     print("welcome to index page")
26
27 @auth(auth_type="local")  #带参数装饰器
28 def home():
29     print("welcome to home page")
30     return "from home"
31
32 @auth(auth_type="ldap")   #带参数装饰器
33 def bbs():
34     print("welcome  to bbs page")
35
36 index()
37 home()
38 bbs()

2、列表、元组、字典中的深copy、浅copy如何理解？

import copy
name1 = [‘a‘,‘b‘,[‘m‘,‘n‘],‘c‘]
name2 = copy.copy(name1)
name3 = copy.deepcopy(name1)
print(name1）
print(name2)
print(name3)

name1[0] = ‘h‘
name1[2][0] = ‘M‘
print(name1）
print(name2)
print(name3)
结果：
[‘a‘, ‘b‘, [‘m‘, ‘n‘], ‘c‘]
[‘a‘, ‘b‘, [‘m‘, ‘n‘], ‘c‘]

[‘h‘, ‘b‘, [‘M‘, ‘n‘], ‘c‘]
[‘a‘, ‘b‘, [‘M‘, ‘n‘], ‘c‘]
[‘a‘, ‘b‘, [‘m‘, ‘n‘], ‘c‘]
