How to get shell output into python after it has run the bash command

Question

Anyone know how to get the output of a python bash code back into python?

I am running:

import subprocess
output = subprocess.run("ls -l", shell=True, stdout=subprocess.PIPE, 
universal_newlines=True)
print(output.stdout)

how do I get the output of ls -l back into my python code? I can have it dump into a file and then call on that file in my python code but is there an easier way, where my code can then directly read the output, without the additional file?

Thank you in advance.

You could use subprocess.getoutput.

subprocess.getoutput("ls -l")

The function returns a string, which then you can parse.

Thank you! The thing is the output will be a password! Which then I am feeding to another method for authentication. Can I parse a password, will it still work?

@artemisia480 If you want to get a password from a user, it is better to use getpass module

no it's not a password from the usr, the link I am running generates a password. I have updated the question, hope that makes things more clear. Thank you again everyone!!!
