I have tried both and Popen2.popen2().
os.popen runs both way, contrary to docs.
# master.py
import os
# both lines work same
#xx= os.popen("/mnt/mass/py/z6.py").readlines()
xx= os.popen("/mnt/mass/py/z6.py",'r',1).readlines()
readlines() returns only when all the lines have been read, which is
when the child quits and the pipe closes. Try reading only one line at a
time. When the pipe closes the readline() will return ''.
# I had hoped small buffer would force a sync (flush())
# No such luck.
for i in xx:
print "\t"+i[:-1]
#"""
# end of file
The "\t" is to prove where the screen output came from.

Nonsense. The minimal Tkinter program is
from Tkinter import Tk
root = Tk()
root.mainloop()
Just to be clear, that's as much a minimal program as

# child.py
import os
import sys
import array
from array import *

from Tkinter import *
from Tkconstants import *
#
def AttPanel():
def PlaceIt():
sys.stdout.write( "Switching to ESRI for placement\n")
sys.stdout.flush()
sys.stdout.flush()
No need to flush twice in a row.
#print "Switching to ESRI for placement"
##zatt= bl_x+bl_y+acrs+c1+c2[2:]+c3[2:]+'\n'
zatt='123456\n'
#print zatt
sys.stdout.write(zatt)
sys.stdout.flush()
#set system variable to zatt
root.withdraw()
#root.iconify()
while raw_input() != ' ':
pass
root.deiconify()

print "\nCRASH Initiated\n"
exit(1)
