hi. in perl i can do this:
... if (open (MYPIPE, "*some_system_command* |")) { ... *do_something* ... while ($answer = <MYPIPE>) { print $answer; } ... *do_something_more* ... } else { ... *do_something_else* ... } ... but i do not know how to do it in python, because "if *command*:" gives syntax error. moreover, if i use ... import os ... try: MYPIPE = os.popen("*some_system_command*, "r") ... *do_something* ... for answer in MYPIPE: print answer, MYPIPE.close() ... *do_something_more* ... except: ... *do_something_else* ... ... it doesn't work, since "*do_something*" and *do_something_more* are always executed (it seems like MYPIPE = os.popen("*some_system_command*", "r") does not raise any exception even if *some_system_command* does not exist/work... any help? thanks a lot max -- http://mail.python.org/mailman/listinfo/python-list
