It is convenient to develop applications in this way, but we need to disable the debug mode in the production environment. Let's create another STARTUP script file to set off dubug mode (filerunp. py ): #!flask/bin/pythonfrom app import appapp.run(debug = False) Restart the application now: ./runp.py Now, rename the Second Acco

Python uses the flask framework to operate sqlite3 in two ways: flasksqlite3 This article describes two methods for using the flask framework to operate sqlite3 in Python.

'] = 'example.com'from modules import memberapp.register_blueprint(member, subdomain=' ') The difference between this code and the first section is that subdomain uses dynamic parameters. (The URL variable in the route is also in this way ). We can use this parameter to obtain relevant users by using the combined url processor before the callback function is requested. In this way, we can access the member module in the form of * .example.com. The following is a convenient function
