We can make use of the Python subprocess module to spawn new processes and connect to their input/output/error pipes, and obtain their return codes.
Subprocess Popen Class
The subprocess.Popen() constructor is responsible for the creation and management of the sub-processes in this Subprocess module.
Example Subprocess Module:
import subprocess
ls_command = ["ls", "-ltrh"]
process = subprocess.Popen(ls_command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
stdout, stderr = process.communicate()
print("Process Standard Output:")
print(stdout)
print("Process Standard Error:", stderr)
print("Process Return Code:", process.returncode)
Output:
Process Standard Output:
total 4.0K
drwxr-xr-x 1 root root 4.0K Aug 9 13:37 sample_data
Process Standard Error:
Process Return Code: 0
