Section 1: Using modules

In this section, you'll learn how to use Python's "import" statement — what it does, how it searches for modules, and how to use data and functions within those modules.

Section 2: Writing modules

In this section, you'll learn how to write modules. Moreover, you'll learn how Python knows whether it has already imported a module, and how the special __name__ variable allows us to make decisions when our module is imported

Section 5: Packages

In this section, we'll learn about Python's "packages," which allow us to create collections of modules for easier maintenance and distribution.

Section 7: Distributions

In this section, we get a taste of how to publish own own packages to PyPI. I use "Poetry" in this section, and both develop and publish a package of my own.
