Python waiting function... sort of?


Sorry about the vague subject but I am having trouble describing my needs here.
I am trying to get a python script(We will call it script A) to call another script(Script B), I need Script A to wait until Script B produces some output then process the output accordingly.
I am using popen() currently. I might just be using it incorrectly for what I need to do. Here is what is going on...


Code:
 def main():
        lircInput = os.popen("/usr/bin/ircat test")
        if lircInput == "left":
                left()
        else:
                right()
this is just for the testing purposes, but left() and right() both recall my main() function when they are done.

Any help would be great. Thanks.

Well you could...

Code:
def main():
os.popen("/usr/bin/ircat test")
        while True:
               
               if lircInput == "left":
                     left()
               else:
                     right()
I don't know how you'll feel about that. Maybe the program is always running, maybe its not.
