We’ve reached the point in which we are ready to gather all new facts and tools and glue all these pieces into one functional block. You already know how HTTP works, how it’ is mounted on top of the TCP stack and how the HTTP server is able to do much more for us than just store and publish fancy ima
PEP 257?
PEP 257 is a document created as part of the Python Developer's Guide, which makes an attempt to standardize the high-level structure of docstrings. It outlines the **conventions**, best practices, and semantics (no... de using docstrings. In short, it tries to answer the following two questions:

We have reached the point where we can start the final stage of our journey – we know enough to communicate with the web service using JSON as an information carrier.

A decorator is one of the design patterns that describes the structure of related objects. Python is able to decorate functions, methods, and classes.
The decorator's operation is based on wrapping the original function with a new "decorating" function (or

The Python Standard Library provides a useful module called ''logging'' to log events occurring in the application. Logs are most often used to find the cause of an error. By default, Python and its modules provide many logs informing you of the causes of errors. However, it's good practice to
