python - os.popen() fails when taking the program receives input on stdin

Question

I'm attempting to get the terminal width using the following popen call:

rows, columns = os.popen('stty size', 'r').read().split()

This works as expected, unless I attempt to pipe input from stdin.

$ echo test | ./test.py 
stty: 'standard input': Inappropriate ioctl for device

Is there a way to make this work? Thanks!
