randint

In the process of learning machine learning algorithms, we often need data to validate algorithms and debug parameters. But it's not that easy to find a set of data samples that are perfectly suited to a particular type of algorithm. Fortunately

Target: Use python to write something that automatically accesses the webpage. Python is really powerful enough. I have improved myself by referring to an excellent python video training program on the Internet. To enable python to open the browser
