Visual Studio Code: enable Python debugging and selecting the Python version used
Posted by jpluimers on 2019/12/18
A few links and screenshots for my archive (assuming development on MacOS):
Enable Python Debugging
- Start the debugger: key combination Shift-Command-D, or click the debug icon
- Click on the wheel with the red dot in the debugger pane:
, which will generate and open a launch.jsonfile in the current workspace, remote the red dot
and fill the drop down with debug configurations

Selecting the Python version
- Key combination Ctrl-Shift-P
- Type
Select Interpreter
- Select the Python version you want; on my system they were at the time of writing:

Setting command-line arguments
Commandline arguments are set in the same .vscode/launch.json file:
"args": [
"--quiet", "--norepeat"
],
Though [WayBack] Python debugging configurations in Visual Studio Code: args could have been more clear that you should put that under the Python configuration section you are debugging with, for instance:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File (Integrated Terminal)",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"args": [
"--quiet", "--norepeat"
]
},
Setting the startup python program
The page above also has a section on [WayBack] Python debugging configurations in Visual Studio Code: _troubleshooting that you can use to start the same script each time you debug, for instance your integration tests:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File (Integrated Terminal)",
"type": "python",
"request": "launch",
// "program": "${file}",
"program": "${workspaceFolder}/snapperListDeleteFailures.FileTests.py",
Fazit
I should have read [WayBack] Get Started Tutorial for Python in Visual Studio Code first.
