Send value of variable that is in a loop from one script to another script

Question

I\'ve been fiddling with sending a variable from one script to another and have done some basic things pretty easily, but I have gotten stuck and was hoping to get some input.

Answer 1

main.py

from subprocess import Popen, PIPE
import sys

p = Popen(['py', 'client.py'], stdout=PIPE)
while True:
    o = p.stdout.read(1)
    if o:
        sys.stdout.write(o.decode('utf-8'))
        sys.stdout.flush()
        print '*'
    else: break

client.py

import time
for a in xrange(3):
    time.sleep(a)
    print a

OUT:

0*
*

*
1*
*

*
2*
*
