Description
1. 关于装饰器
在监听好友消息并回复分析处理后结果的学习中,有一段示例代码:
@bot.register(Group, TEXT)
def print_group_msg(msg):
print(msg)
这里出现了一个用法为 @bot.register() ,之前的教程中尚未涉及到这一部分,后来翻看了笑来老师的书,其中讲到了装饰器。
@bot.register() 在python中这种语法被称为装饰器(decorator)。它的作用是将 print_group_msg()函数当做一个参数传给bot.register()函数。
更多详细内容,可以参考笑来老师书中的装饰器章节:
https://github.com/selfteaching/the-craft-of-selfteaching/blob/master/Part.3.B.3.decorator-iterator-generator.ipynb
2. 关于import... 和 from...import...
今天的作业中,如果直接使用 from wxpy import * , 会提示异常如下:

这是因为导入的模块中,很多子类没有用到,但这并不影响程序的运行。
如果想去掉这些异常的提示,可以使用
from wxpy import Bot,Message,embed , 只导入用到的类和方法。
另外,还可以直接使用 import wxpy ,但在使用其中的子类和方法时,都必须增加wxpy.前缀。
以上描述如果有错误还请大家指正,对这些问题同样有疑问的也欢迎一起交流 😄 。

Research direction
Start with the Day12 wxpy lesson and the referenced Part.3.B.3.decorator-iterator-generator.ipynb notebook, then compare the decorator and import explanations with the examples in this issue. Done means the lesson clearly explains @bot.register() and the supported import forms, including the reported warning behavior.
