There is a famous saying about Python: don't reinvent the wheel.
But there are three problems:
1. You don't know which wheels are already built and which ones are suitable for you. There are more than 400 famous wheels with names and surnames, not to mention the wheels that have no name or name and are in the making.
2. It is true that the wheels are not repeated, but the cars are repeated. Including hundreds of lines of code written by many great gods, in order to solve a mature function that Excel itself has.
3. Many people use it to capture pictures, data, pictures, videos and weather forecasts to entertain themselves, and then what? What will you do with the big data? For example, so-and-so beer sells fast, and then what? For example, a certain movie has a lot of box office, and then what?
The following is the code that has been debugged with Python 3.6.4 and shared with you:
1. Grab Zhihu pictures
2. Listen to two chatbots chatting with each other
3. AI analyzes whether the author of Tang poetry is Li Bai or Du Fu
4. The lottery randomly generates 7 out of 35
5. Automatically write a review letter
6. Screen recorder
7. Make Gif animations
① Grab Zhihu pictures with only 30 lines of code

以下是样稿：
请输入具体事件：抽烟
老师要求的字数：200
检讨书
老师：
我不应该抽烟， 学校一开学就三令五申，一再强调校规校纪，提醒学生不要违反校规，可我却没有把学校和老师的话放在心上，没有重视老师说的话，没有重视学校颁布的重要事项，当成了耳旁风，这些都是不应该的。同时也真诚地希望老师能继续关心和支持我，并却对我的问题酌情处理。 无论在学习还是在别的方面我都会用校规来严格要求自己，我会把握这次机会。 但事实证明，仅仅是热情投入、刻苦努力、钻研学业是不够的，还要有清醒的政治头脑、大局意识和纪律观念，否则就会在学习上迷失方向，使国家和学校受损失。
再次请老师原谅！
