I am trying to use and manipulate output from subprocess.check_output() in python but since it is returned byte-by-byte
for line in output:
# Do stuff
Does not work. Is there a way that I can reconstruct the output to the line formatting that it has when it is printed to stdout? Or what is the best way to search through and use this output?
Thanks in advance!

The subprocess. check_output() is used to get the output of the calling program in python. It has 5 arguments; args, stdin, stderr, shell, universal_newlines. The args argument holds the commands that are to be passed as a string.
CalledProcessError Exception raised when a process run by check_call() or check_output() returns a non-zero exit status. returncode Exit status of the child process.
To capture the output of the subprocess. run method, use an additional argument named “capture_output=True”. You can individually access stdout and stderr values by using “output. stdout” and “output.
subprocess.check_output() returns a single string. Use the str.splitlines() method to iterate over individual lines in that string:
for line in output.splitlines():
