General

• dabeaz-course/python-mastery • Advanced Python mastery course

macOS setup

• Install pyenv
  • brew install pyenv + brew install pyenv-virtualenv
    • confirm what I added in the end
• Install Python using pyenv
  • do not brew install python or brew install python3
    • confirm if it’s installed
• Set up VS Code
  • Add Python extension to VS Code
  • hopefully this doesn’t happen to you, but it did to me: if trouble with the Python extension (Python not added to the file language options list, python commands not working in integrated terminal):
    • completely uninstall VS code (via AppCleaner + Homebrew uninstall + rm -rf ~/.vscode)
    • start a new VS install (via Homebrew) from scratch
    • carefully add one extension and setting at a time + settings sync as you go after each change

Pyenv

• Version management for Python projects, similar to NVM for Node.js
• Managing Multiple Python Versions With pyenv • Real Python 📖

Functions

Positional vs Keyword Arguments

• The advantage of using keyword arguments is that the caller of the function can specify them in any order.
• The advantage of using positional arguments is that the caller of the function doesn’t need to know the names of the arguments.
• In general, it’s best to use keyword arguments for optional arguments and positional arguments for required arguments.
