To do this, use the variable DEBUGPY_EXTRA_ARGV and add whatever command-line switches you like. For example, set DEBUGPY_EXTRA_ARGV=--connect 5678 will allow you to omit the --connect switch from the command line. If the same switch is found on both the command line and the environment, the one from the environment is ignored.

Debugging a script file
To run a script file with debugging enabled, but without waiting for the client to attach (i.e. code starts executing immediately): To wait until the client attaches before running your code, use the --wait-for-client switch. The hostname passed to --listen specifies the interface on which the debug adapter will be listening for connections from DAP clients. It can be omitted, with only the port number specified: in which case the default interface is 127.0.0.1. To be able to attach from another machine, make sure that the adapter is listening on a public interface - using 0.0.0.0 will make it listen on all available interfaces: This should only be done on secure networks, since anyone who can connect to the specified port can then execute arbitrary code within the debugged process. To pass arguments to the script, just specify them after the filename. This works the same as with Python itself - everything up to the filename is processed by debugpy, but everything after that becomes sys.argv of the running process.
Debugging a module
To run a module, use the -m switch instead of filename: Same as with scripts, command line arguments can be passed to the module by specifying them after the module name. All other debugpy switches work identically in this mode; in particular, --wait-for-client can be used to block execution until the client attaches.
Attaching to a running process by ID
The following command injects the debugger into a process with a given PID that is running Python code. Once the command returns, a debugpy server is running within the process, as if that process was launched via -m debugpy itself.
Enabling debugging
At the beginning of your script, import debugpy, and call debugpy.listen() to start the debug adapter, passing a (host, port) tuple as the first argument. As with the --listen command line switch, hostname can be omitted, and defaults to "127.0.0.1":
Waiting for the client to attach
Use the debugpy.wait_for_client() function to block program execution until the client is attached.
breakpoint() function
Where available, debugpy supports the standard breakpoint() function for programmatic breakpoints. Use debugpy.breakpoint() function to get the same behavior when breakpoint() handler installed by debugpy is overridden by another handler. If the debugger is attached when either of these functions is invoked, it will pause execution on the calling line, as if it had a breakpoint set. If there's no client attached, the functions do nothing, and the code continues to execute normally.
To enable debugger internal logging via CLI, the --log-to switch can be used:
When using the API, the same can be done with debugpy.log_to():
In both cases, the environment variable DEBUGPY_LOG_DIR can also be set to the same effect.
When logging is enabled, debugpy will create several log files with names matching debugpy*.log in the specified directory, corresponding to different components of the debugger. When subprocess debugging is enabled, separate logs are created for every subprocess.
Apr 18, 2024 · Ubuntu for the virtual machine is convenient because Python is installed by default. If you have a different configuration, see Install Python interpreters for other Python download locations. Configure the firewall. The inbound port 5678 must be open on the remote computer's firewall to support remote debugging.
An implementation of the Debug Adapter Protocol for Python. copied from cf-staging / debugpy
Jan 30, 2019 · Yes! There's a Python debugger called pdb just for doing that! You can launch a Python program through pdb via python -m pdb myscript.py. There are a few commands you can then issue, which are documented on the pdb page. Some useful ones to remember are: b: set a breakpoint; c: continue debugging until you hit a breakpoint; s: step through the code
