None

Summary of the issue:

When generating a syntax erro in a Python 3.13 Python console, the following is logged:

ERROR - unhandled exception (09:14:31.494) - MainThread (11952):
Traceback (most recent call last):
  File "code.pyc", line 65, in runsource
  File "pythonConsole.pyc", line 143, in __call__
  File "codeop.pyc", line 155, in __call__
  File "codeop.pyc", line 75, in _maybe_compile
  File "codeop.pyc", line 118, in __call__
  File "<console>", line 1

SyntaxError: invalid syntax

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "code.pyc", line 68, in runsource
TypeError: PythonConsole.showsyntaxerror() got an unexpected keyword argument 'source'

Description of user facing changes:

Python console no longer breaks on syntax errors on Python 3.13 builds.

Description of developer facing changes:

None

Description of development approach:

Python 3.13 added **kwargs to the showsyntaxerror method. Adding this shouldn't do any harm on Python 3.11. kwargs will always be empty there and it's not problematic to pass a **kwargs to a non-kwargs supporting function when kwargs is empty.

Testing strategy:

• Test generating a syntax error on Python 3.11 builds
• Test generating a syntax error on Python 3.13 builds
