1. Debugger not working

Unfortunately there could be a number of reasons why the debugger isn’t working.
For instance it is possible VS Code is displaying some errors that could provide a hint. Look at the debugger console for any error messages displayed. Look at the Debugger Tools console output for any errors.

Cause: The path to the python executable is incorrect
Solution: Configure the path to the python executable in the launch.json
Remember to re-start VS Code once done (this won’t be necessary in a future release).

Cause: Invalid expressions in watch window
The following error is displayed:

Traceback (most recent call last):
  File ".../visualstudio_py_debugger.py", line 1646, in loop
    cmd()
  File ".../visualstudio_py_debugger.py", line 1918, in command_execute_code
    thread.run_on_thread(text, cur_frame, eid, frame_kind, repr_kind)
  File ".../visualstudio_py_debugger.py", line 1246, in run_on_thread
    self.schedule_work(lambda : self.run_locally(text, cur_frame, execution_id, frame_kind, repr_kind))
  File ".../visualstudio_py_debugger.py", line 1238, in schedule_work
    self.unblock()
  File ".../visualstudio_py_debugger.py", line 1234, in unblock
    self._block_lock.release()
RuntimeError: release unlocked lock

Solution: Clear all expressions from the debugger Watch window and start debugging again.

2. Unable to capture user input while debugging

Capturing user input while debugging is only possible when using the Python Console App debug configuration.

Cause: Visual Studio Code Debug output window doesn’t support capturing input from the user
Solution: Select the Python Console App debug configuration
