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

I finally got it to work. Thanks to going back and forth with Vadim, I was able to learn how some of this stuff works. Below is what my code is.

script1.py:

import sys, time
x=0
while x<10:
    print(x)
    sys.stdout.flush()
    x = x+1
    time.sleep(1)

script2.py:

import subprocess

proc = subprocess.Popen('python script1.py', 
                        shell=True,
                        stdin=subprocess.PIPE,
                        stdout=subprocess.PIPE,
                        )
while True:
    output = proc.stdout.readline()
    if output == '':
        break
    else:
        print output.rstrip()

Output:

0 #waits one second
1 #waits one second
2 #waits one second
.

.
8 #waits one second
9 #waits one second

Answer 2

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*
*
