In the previous article we elaborated on how to use Pymongo in Python to manipulate the MongoDB database, but directly to the database operation code written in the script, it is obvious that the application of the code coupling is too strong, and not conducive to the optimization of code management, General a

After finishing the front-end html design, Tom immediately began to design the database structure.
Before he started, Tom recalled the database design explanation that the boss talked about during training at the company:

with a different package name. In our case, we found a suitable directory in Pythonpath and created a webservices package that put soap.py in the package. So, in Linux:
$ mkdir ~/lib/python/webservices
$ touch ~/lib/python/webservices/__init__.py
$ cp soappy097/soap.py ~/lib/ Python/webservices

you want to write a script to pop up a CD driver, or a Web service to delete a cache file in the/tmp directory, or a socket service to bind a TCP port, these calls are not expected in your unit testing.
As a developer, you are more concerned about whether your library has successfully called system functions to eject CDs, rather than experiencing each test with the CD tray open.
As a developer, you are more concerned about whether your library has su
, so in the process of program development, improve the interface, user interaction process and other elements without rewriting the entire program logic, just replace the relevant part of it.Installation of a Python virtual environmentA long time ago, the first time I learned Python, I saw virturalenv this thing. The virtual environment was not a priority at the time, but it was best to use the virtual env
application. I've also used similar code in this tutorial, so if you've just contacted flask or python, you can use Docker instead of virtualenv to continue learning based on the tutorials mentioned above.
In order for it to run inside the Docker container, we also need to do some operations. In our instance Apache server, the Example_app.wsgi file contains instructions to connect to the
