Python debugging in VS Code. The Python extension supports debugging through the Python Debugger extension for several types of Python applications. For a short walkthrough of basic debugging, see Tutorial - Configure and run the debugger. Also see the Flask tutorial. Both tutorials demonstrate core skills like setting breakpoints and stepping ...

Debugging Python code in VSCode is a powerful way to understand and fix issues in your code. By following the steps you can effectively setup and start you debugging journey in ...
Jan 2, 2019 · Thanks. If we add python.pythonPath to settings.json, it works.But, I just want to add another way which is making the same thing. Use the Python: Select Interpreter command from the Command Palette (Ctrl+Shift+P) and select the python interpreter that belongs to the new virtual environment.

Visual Studio can launch and debug Python applications locally and remotely on a Windows computer (see Remote debugging). It can also debug remotely on a different operating system, device, or Python implementation other than CPython using the debugpy library.
When using debugpy, the Python code being debugged hosts the debug server to which Visual Studio can attach. This hosting requires a small modification to your code to import and enable the server, and may require network or firewall configurations on the remote computer to allow TCP connections.
The following items are needed to follow this walkthrough:
•A remote computer running Python on an operating system like Mac OSX or Linux.
•Port 5678 (inbound) opened on that computer's firewall, which is the default for remote debugging.
You can easily create a Linux virtual machine on Azure and access it using Remote Desktop from Windows. Ubuntu for the VM is convenient because Python is installed by default; otherwise, see the list on Install a Python interpreter of your choice for additional Python download locations.
1.On the remote computer, create a Python file called guessing-game.py with the following code:
2.Install the debugpy package into your environment using pip3 install debugpy.
3.Enable remote debugging by adding the code below at the earliest possible point in guessing-game.py, before other code. (Though not a strict requirement, it's impossible to debug any background threads spawned before the listen function is called.)
4.Save the file and run python3 guessing-game.py. The call to listen runs in the background and waits for incoming connections as you otherwise interact with the program. If desired, the wait_for_client function can be called after listen to block the program until the debugger attaches.
In these steps, we set a simple breakpoint to stop the remote process.
1.Create a copy of the remote file on the local computer and open it in Visual Studio. It doesn't matter where the file is located, but its name should match the name of the script on the remote computer.
2.(Optional) To have IntelliSense for debugpy on your local computer, install the debugpy package into your Python environment.
3.Select Debug > Attach to Process.
4.In the Attach to Process dialog that appears, set Connection Type to Python remote (debugpy).
5.In the Connection Target field, enter tcp:// :5678 where is that of the remote computer (which can be either an explicit address or a name like myvm.cloudapp.net), and :5678 is the remote debugging port number.
Visual Studio 2017 versions 15.8 and later use a debugger based on ptvsd version 4.1+. Visual Studio 2019 versions 16.5 and later use a debugger based on debugpy. These versions of the debugger are compatible with Python 2.7 and Python 3.5+. If you're using Python 2.6, 3.1 to 3.4, or IronPython, Visual Studio shows the error, Debugger does not support this Python environment. The following information applies only to remote debugging with ptvsd 3.x.
1.With ptvsd 3.x, the enable_attach function required that you pass a "secret" as the first argument that restricts access to the running script. You enter this secret when attaching the remote debugger. Though not recommended, you can allow anyone to connect, use enable_attach(secret=None).
2.The connection target URL is tcp:// @ :5678 where is the string passed enable_attach in the Python code.
By default, the connection to the ptvsd 3.x remote debug server is secured only by the secret and all data is passed in plain text. For a more secure connection, ptvsd 3.x supports SSL using the tcsp protocol, which you set up as follows:
1.On the remote computer, generate separate self-signed certificate and key files using openssl:
When prompted, use the hostname or IP address (whichever you use to connect) for the Common Name when prompted by openssl.
Remote debugging. VS Code does not support built-in remote debugging across all languages. Remote debugging is a feature of the debug extension you are using, and you should consult the extension's page in the Marketplace for support and details. There is, however, one exception: the Node.js debugger included in VS Code supports remote debugging.

Jun 24, 2024 · The following step-by-step guide helps you to set up VSCode correctly for running Python code. Step 1: Select python interpreter. A system can have multiple Python interpreters. Using the right interpreter for your project is important since VSCode uses it to run and debug your code and provide things like auto-completion.
