Creating a Python .gitignore from a template via a keyboard shortcut

Save the template to a central location e.g. C:\Users\nyep\<username>\templates.

Create a new task in tasks.json in VS Code, replacing <file path> with the actual path to your templates folder:

...
{
    "label": "Add .gitignore from template",
    "type": "shell",
    "command": "Copy-Item -Path '<file path>>\\.gitignore' -Destination '${workspaceFolder}\\.gitignore'",
    "presentation": {
        "reveal": "silent",
        "panel": "shared"
    }
}
...

Add a key binding in keybindings.json:

...
{
    "key": "ctrl+f1",
    "command": "workbench.action.tasks.runTask",
    "args": "Add .gitignore from template"
}
...
