Python packaged crawler using tkinter graphical interface

The general function of this project is to enter the user's account password in the window, crawl the information and display it through tkinter, as shown in the figure:

The crawler part is omitted, mainly to simply encapsulate the crawler function, enter the user account password, and then display the crawled information
