subprocess.CompletedProcess

class subprocess.CompletedProcess

The return value from run(), representing a process that has finished.

args

The arguments used to launch the process. This may be a list or a string.

returncode

Exit status of the child process. Typically, an exit status of 0 indicates that it ran successfully.

A negative value -N indicates that the child was terminated by signal N (POSIX only).

stdout

Captured stdout from the child process. A bytes sequence, or a string if run() was called with universal_newlines=True. None if stdout was not captured.

If you ran the process with stderr=subprocess.STDOUT, stdout and stderr will be combined in this attribute, and stderr will be None.

stderr

Captured stderr from the child process. A bytes sequence, or a string if run() was called with universal_newlines=True. None if stderr was not captured.

check_returncode()

If returncode is non-zero, raise a CalledProcessError.
