How do I let Python see what Terminal outputs when I enter a command?

Question

I want to run a program on Python on macOS Sierra that checks Terminal for its outputs after I automatically enter a command on it. For example, I would write in Terminal:

$ pwd

and then Terminal would output something like:

/Users/username

How would I have Python scan what Terminal outputs and set it to a variable as a string?

>>>output = (whatever Terminal outputs)
>>>print (output)
"/Users/username"

By the way, the other forums do not explain in much detail how one would do this in macOS. Therefore, this is not a duplicate of any forum.

Answer 1

You could pipe the output to a file and read the file.

$ pwd > output.txt

Then read the file and take further actions based on its contents.
