# Bug report ### Bug description: Playing with the Python 3.13.0 interpreter installed from brew on macOS 14.7 in a Terminal window. I entered the repl and typed ```python >>> import math >>> math.tau 6.283185307179586 ``` Then I hit ctrl-P to get the last line and hit SPC, `/`, `2`. Oddly, the SPC got eaten and the slash ended up right next to the `u`. I didn't notice that until I hit Enter, at which point the exception occurred and exited the interpreter. Unfortunately, I cannot reproduce it again. ```python % python3 Python 3.13.0 (main, Oct 7 2024, 05:02:14) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import math >>> math.tau 6.283185307179586 >>> math.tau/ 2 SyntaxError: source code string cannot contain null bytes (<python-input-2>) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<frozen runpy>", line 198, in _run_module_as_main File "<frozen runpy>", line 88, in _run_code File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/_pyrepl/__main__.py", line 6, in <module> __pyrepl_interactive_console() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^ File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/_pyrepl/main.py", line 59, in interactive_console run_multiline_interactive_console(console) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^ File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/_pyrepl/simple_interact.py", line 160, in run_multiline_interactive_console more = console.push(_strip_final_indent(statement), filename=input_name, _symbol="single") # type: ignore[call-arg] File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/code.py", line 313, in push more = self.runsource(source, filename, symbol=_symbol) File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/_pyrepl/console.py", line 179, in runsource self.showsyntaxerror(filename, source=source) ~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/_pyrepl/console.py", line 165, in showsyntaxerror super().showsyntaxerror(filename=filename, **kwargs) ~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/code.py", line 115, in showsyntaxerror self._showtraceback(typ, value, None, source) ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/Cellar/python@3.13/3.13.0_1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/code.py", line 140, in _showtraceback and not value.text and len(lines) >= value.lineno): ^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: '>=' not supported between instances of 'int' and 'NoneType' ``` ### CPython versions tested on: 3.13 ### Operating systems tested on: macOS <!-- gh-linked-prs --> ### Linked PRs * gh-125732 * gh-126023 <!-- /gh-linked-prs -->
