Answer a question

Other IDE's like PyCharm, IntelliJ, etc. have a feature where if it finds a function being called that is undefined, you can right-click it and click 'create method' or something similar to automatically create the function definition. It helps out a lot in TDD. Is there something similar in VS Code?

You can install the My Code Actions extension, here is a simple example:

Configure in settings.json file:

// settings.json file
{
    "my-code-actions.actions": {
        "[python]": {
        "create new methond {{diag:$1}}": {
            "diagnostics": ["\"(.*?)\" is not defined"],
            "text": "def {{diag:$1}}():\n    pass\n",
            "where": "afterLast",
        }
        }
    }
}

The effect when writing code after saving this setting:

Another method that might be useful:

open in sequence File > Preferences > Configure User Snippets. Select python in the command palette. This will create a python.json file in which you can customize the code segment according to the rules.

A simple example:

    "Print to console":{
        "prefix": "defHello",
        "body": [
            "def Hello():",
            "${1:    }print('Hello worle')",
            "$2",
        ],
        "description": "print hello world"
    }
