Python: Streaming Input with Subprocesses
- by beary605
Since input and raw_input() stop the program from running anymore, I want to use a subprocess to run this program...
while True: print raw_input()
and get its output.
This is what I have as my reading program:
import subprocess
process = subprocess.Popen('python subinput.py', stdout=subprocess.PIPE, stderr=subprocess.PIPE)
while True:
output=process.stdout.read(12)
if output=='' and process.poll()!=None:
break
if output!='':
sys.stdout.write(output)
sys.stdout.flush()
When I run this, the subprocess exits almost as fast as it started. How can I fix this?
