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.
