[issue42388] subprocess.check_output(['echo', 'test'], text=True, input=None) fails

[Gregory P. Smith]

Gregory P. Smith <greg at krypto.org> added the comment:

Meta issue behind this one: The input= behavior on check_output is yet another unfortunate wart in the subprocess collection of APIs.

PR to the main branch is in, 3.9 and 3.8 will automerge after CI runs.
