Tested on Ubuntu 22.04:
>>>importos>>>os.posix_spawn("/bin/echo", ["echo","hi"],os.environ,scheduler=None)Traceback (mostrecentcalllast):File"<python-input-1>",line1,in<module>os.posix_spawn("/bin/echo", ["echo","hi"],os.environ,scheduler=None)~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^SystemError:newstylegetargsformatbutargumentisnotatuple
