Resources for Pip

We implement our own command in Python and distribute it via pip with pip install sheet2graph.

The command takes spreadsheets files (csv, xlsx) as input, and generates images (png, jpg, svg) based on the data contained.

We save out first graph from the spreadsheet data.

• Installing Plotly to generate graphs
• Pip freeze requirements
• Solving dependency problems
• Using Pandas to do simple data processing

We start refactoring what we have until now, and add type annotations.

• Add basic annotations to functions
• Use Typeguard to enforce the annotations at runtime
• Annotations as a kind of documentation
• Add a new type of graph: the scatter graph

We will add support for Excel files (.xlsx).

• add dependencies: Openpyxl and Xlrd for Excel support
• Fix type errors

We will start preparing our command for distribution in pypi for it to be installable with pip, and testing the distribution in a test environment.

• Finding a proper name for our command
• Folder structure and necessary files
• Changes in the entry point of our program
• Generating a good README file in Markdown
• Examples and documentation

• Choosing a license
• Dependencies and versioning
• Setup.cfg and setup.py

After testing at test.pypi.org, we will fix an error with the example image in the documentation and distribute our command 'sheet2graph' to the real production environemnt at pypi.org.

• Fixing error with images in README.md at test.pypi.org
• Creating a new account at production (pypi.org)
• New secure tokens in .pypirc or interactively for production
• Solving problems with secure tokens

In this episode we put everything together and install our own command by typing 'pip install sheet2graph'. We test it both in a virtual environment and globally. We also talk about what this means to distribute code you develop easily to the world, something that now should be a lot more approachable. As always, we need to be mindful of publishing useful and tested code, and in general to play well within the ecosystem.
