To Build on Rob's Answer, you can also set a shortcut key combination to trigger each task by adding to keybindings.json, e.g.

{
    "key": "ctrl+h",
    "command": "workbench.action.tasks.runTask",
    "args": "Run tests"
}

where the args component is replaced with the task name.

You could use this in combination with ${file} in tasks.json to differentiate between the separate build types.

e.g. hit Ctrl+h for python and Ctrl+Shift+h for tsc

Answer 2

You can use the ${file} wildcard to pass the current file to your build program/script.

There's an example given in the docs for TS: https://code.visualstudio.com/Docs/editor/tasks#_operating-system-specific-properties

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "presentation": {
        "panel": "new"
    },
    "tasks": [
        {
            "taskName": "TS - Compile current file",
            "type": "shell",
            "command": "tsc ${file}",
            "problemMatcher": [
                "$tsc"
            ]
        }
    ]
}
