The shortest way to get a complete pack of VSCode and Python on Windows PC.

1.Preparing Git

• Open the link: get-git
• Run the installer
• Select “Use Git and optional Unix tools from the Command Prompt” during an installation process

2.Preparing pyenv

cmd
git clone https://github.com/pyenv-win/pyenv-win.git %USERPROFILE%/.pyenv

3.Modify PATH env

• System Properties > Advanced > Environment Variables > User variables for %USERNAME%
• Add to PATH:
  • %USERPROFILE%.pyenv\pyenv-win\bin
  • %USERPROFILE%.pyenv\pyenv-win\shims

4.Installing Python

cmd
pyenv install 3.7.3-amd64

5.Installing poetry (project management), flake8 (code-style) and yapf (auto-formatting)

cmd
pyenv global 3.7.3-amd64
python -m pip install poetry flake8 yapf

6.Installing VS Code

• Open the link: get-vscode

7.Adding Python support

• Run VS Code
• Press Ctrl+Shift+X
• Type “python”
• Press “Install”

8.Configuring VS Code global settings

• Open VS Code
• Press Ctrl+Shift+P and type “Open User Settings”, press Enter.
• Paste:

{
    "files.encoding": "utf8",
    "editor.rulers": [79],
    "python.linting.enabled": true,
    "python.linting.pep8Enabled": false,
    "python.linting.pylintEnabled": false,
    "python.linting.flake8Enabled": true,
    "python.linting.flake8CategorySeverity.E": "Warning",
    "python.linting.flake8CategorySeverity.F": "Warning",
    "python.linting.flake8CategorySeverity.W": "Warning",
    "python.linting.flake8Args": ["--exclude .venv"],
    "python.linting.ignorePatterns": [
        ".git/*",
        ".vscode/*",
        ".venv/*"
    ],
    "python.formatting.provider": "yapf",
}

Now flake8 will automatically shows if any line of code has style mistakes and by pressing Shift+Alt+F it will be solved as possible.

9.Configuring VS Code keyboard shortcuts

• Press Ctrl+Shift+P and type “Open Keyboard Shortcuts File”, press Enter.
• Paste:

[
        {
                "key": "alt+q",
                "command": "python.execInTerminal",
        },
        {
                "key": "alt+w",
                "command": "python.createTerminal"
        }
]

Now you can open python file from the project and:

• Press Alt+Q to execute a file in a terminal;

• Press Alt+W to create a terminal and activate virtualenv.

10.Creating a project

cmd
cd C:/dev/
poetry new project1

11.Creating venv

cd C:/dev/project1
pyenv local 3.7.3-amd64
python -m venv .venv

12.Opening a project

• Open a folder in VS Code
• Press a bottom left button “Select Python Interpreter”
• Choose interpreter from .venv

13.Adding packages in VS Code

• Press Ctrl+`
• Ensure a terminal points to a current project directory
• Type: poetry add package-name (e.g. “poetry add pyyaml”)

14.Ready to code!
