Don't use communicate, it waits for the process to finish.
But you can write and read from the pipes. The hard part is to recognize
*where* output from the previous command ends (so you don't read further). The
code below uses #\n as the prompt:
import subprocess as s
def read_output(stdout):
while 1:
line = stdout.readline()
if not line: break
line = line.rstrip('\r\n')
if line=='#': break
yield line
proc = s.Popen('cmd.exe /k prompt #$_', stdin=s.PIPE, stdout=s.PIPE)
for line in read_output(proc.stdout): pass # skip over initial prompt
while 1:
cmd = raw_input('cmd:')
proc.stdin.write(cmd+'\n')
for line in read_output(proc.stdout):
print line
