Here's some truly minimal code which shows the same buffering behaviour: $ cat master.py #!/usr/bin/env python import os for line in os.popen("./child.py"): print "-->", line.strip() $ cat child.py #!/usr/bin/env python import time for i in range(5): print i time.sleep(.2) On Linux you can work around it with pexpect: $ cat master2.py #!/usr/bin/env python import pexpect for line in pexpect.spawn("./child.py"): print "-->", line.strip() On Windows, I don't know.
