Today, try to write a small demo implementation of the code that was seen before, the purpose of understanding the different files of data access, how to get the foreground data, how to put the database data on the front page display.The AWT visualization interface enables you to submit

actually executes the imported module once, as follows:First look at the module being called test.py :def haha(): print("哈哈")haha()Look at the main program again main.py :import testprint("一条鱼")The execution results are:哈哈一条鱼How can you simply invoke the code without executing the called module? To be called module code is not executed, the premise is to know __name__ what the variable means, in short, if not involved in the module import, __name__ The value is " __main__ ", if the module is

impossible even if the image is slightly complicated. However, when creating a data visualization project with complex interaction logic, the Code complexity of this method will increase with the scale of the interaction logic, and bring about many unexpected program conflicts-all of which are the same reason as the web development field before MVC or the software crisis in 1970s. People of insight had lon
