PyMongo Monday: Setting Up Your PyMongo Environment` focuses on the process of setting up a Python environment to interact with MongoDB using the PyMongo library. The tutorial begins by installing the `m` tool, which allows multiple installations of the MongoDB server to be managed in parallel, and then installs the current stable production version (4.0.2) of MongoDB. It also covers how to use `m` to run the corresponding binary and connect to the database using the `mongo` shell. The tutorial then moves on to installing the PyMongo driver with pip and connecting to the database using Python, including importing the library, creating a local client object, and issuing commands to the server. The conclusion highlights the completion of episode one, which covered setting up the environment, and looks forward to introducing CRUD operations in the next episode.
