How do you run a python program in visual studio

Whenever I hit the f5 key to run a program a new file called launch.json opens and I don't know what to do from there. Does anyone know hat to do and no this is no the same as how do I install python for visual studio. This is what launch.json looks like.

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "program": "${file}",
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput"
            ]
        },
        {
            "name": "Python Console App",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "program": "${file}",
            "externalConsole": true,
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit"
            ]
        },
        {
            "name": "Django",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "program": "${workspaceRoot}/manage.py",
            "args": [
                "runserver",
                "--noreload"
            ],
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput",
                "DjangoDebugging"
            ]
        },
        {
            "name": "Watson",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "program": "${workspaceRoot}/console.py",
            "args": [
                "dev",
                "runserver",
                "--noreload=True"
            ],
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput"
            ]
        }
    ]
}
