[issue25303] Add option to py_compile to compile for syntax checking without writing bytecode

Pavel Roskin added the comment: Thank you for the comments. I was annoyed by py_compile making files with names very similar to the original scripts, names that could not even be recognized by shell patterns in .gitignore unless scripts ending with "c" are banned. But that problem is addressed

[issue25303] Add option to py_compile to compile for syntax checking without writing bytecode

R. David Murray added the comment: OK, I'll change the title to reflect the current proposal, and we'll see if anyone is interested in proposing a patch. The bug with python -m py_compile is when you do: python -m py_compile myscript where myscript is a file containing python code (note t
