apache2ctl configtest

Here is what the above code is Doing:
1. We’re importing the os module, which will allow us to use operating system dependent functionality.
2. We’re importing the sys module, which will allow us to use system specific parameters and functions.
3. We’re importing the subprocess module, which will allow us to spawn new processes, connect to their input/output/error pipes, and obtain their return codes.
4. We’re setting the variable command to the string “apache2ctl configtest”.
5. We’re using the subprocess module to run the command we set in the previous step.
6. We’re using the subprocess module to print the output of the command we set in the previous step.
7. We’re using the subprocess module to print the return code of the command we set in the previous step.
