There's a script that runs all 9 combinations of zip vs. file vs. directory, and no profiling vs. profile vs cProfile. It can be executed via:
updating: __main__.py (stored 0%)
Archive: code.zip
extracting: directory/__main__.py
Python 3.11.0
*** Running without profiling
Hello from __main__.py
Hello from code.zip

Bug report
Python can execute zip files (PEP-441) and directories directly, e.g.
python code.ziporpython directory, if they're constructed appropriately (such as viazipappor https://github.com/pantsbuild/pex). These don't work withprofileorcProfilemodules, e.g.python -m profile code.zipfails withValueError: source code string cannot contain null bytesandpython -m cProfile directoryfails withIsADirectoryError: [Errno 21] Is a directory: 'directory'.For example: https://gist.github.com/huonw/52574abce4057afd99abb5e4a7f82b61 has a simple
