How to get the output from os.system()? [duplicate]
Use subprocess:
import subprocessprint(subprocess.check_output(['nslookup', 'google.com']))If the return code is not zero it will raise a CalledProcessError exception:
try: print(subprocess.check_output(['nslookup', 'google.com']))except subprocess.CalledProcessError as err: print(err)os.system only returns the exit code of the command. Here 0 means success. Any other number stands for an operating-system-dependent error. The output goes to stdout of this process. subprocess intends to replace os.system.
subprocess.check_output is a convenience wrapper around subprocess.Popen that simplifies your use case.
