检测 Python 正在 Visual Studio Code 中运行

Question

There are cases where code needs to act differently if running in Visual Studio Code.

Does anybody know the most efficient way to detect that the python code is running in the Visual Studio Code debugger?

So far, the best way I could find was using:

import sys
if 'debugpy' in sys.modules:
    print("Running in VS Code")

I think the most elegant way to solve this is just to set up a run task in vscode that runs the Python script with an extra command line flag.

for example:

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('--vscode', action='store_true')

args = parser.parse_args()

if args.vscode:
    print("vscode")
else:
    print("not vscode")

then if you call the script python myscript.py

'not vscode'

if you call python myscript.py --vscode

'vscode'

Then you can just add a run task in vscode:

{
    "label": "run",
    "command": "python", // or python3
    "group": {
        "kind": "test",
        "isDefault": true
    },
    "args": [
        "${file}",
        "--vscode"
    ],
    "presentation": {
        "echo": true,
        "panel": "shared",
        "focus": true
    },
    "problemMatcher": []
}

To run your code, just use a shortcut for your run task
