Kindly find below what I'm trying to do and what is my issue.

Goal :
Execute shell command "ls -l" and save the result into a list.

Issue :

Save it into a list -- KO

Other infos :
OS used : Fedora release 26 (Twenty Six)
Python version : Python 3.6.2


Code :

#resultat = subprocess.call(["ls", "-l", "/var/log"])
#resultat = subprocess.Popen(["ls", "-l", "/var/log"], stdout=subprocess.PIPE)
#subprocess.run(["ls", "-l", "/var"], stdout=subprocess.PIPE)
p = subprocess.Popen(["ls", "-l", "/var/log"], stdout=subprocess.PIPE)
#(output, err) = p.communicate()
p_status = p.wait()
for line in p.stdout:
  print (line)

#print ("Command output : ", output)
#output, err = resultat.communicate()


#resultat = subprocess.call(["ls", "-l", "/var/log"])

#print(resultat)
#print(type(resultat))

I am really not familiar with subprocess library nor with Popen constructor and I don't understand them.
I know I should use Popen construtor (import subprocess) and I tried to read several documentation.
Unfortunately, my technical english isn't that good, I couldn't understand them.

Also, my code is kinda random.
As you can see I have tried several method to get a proper print because I didn't really understand how to use the library subprocess.

Could you help me with saving my 'ls -l' command into a list?

Thanks!

Cheers,
