Here's the equivalent for Python 3: >>> import subprocess >>> output = subprocess.getoutput("echo Hello World!") >>> print(output) Hello World! >>> ;) For invoking external programs you should still consider something more involved like >>> p = subprocess.Popen(["grep", "^def\s", "/usr/lib/python3.2/subprocess.py"], stdout=subprocess.PIPE) >>> print(p.communicate()[0].decode("utf-8")) def _cleanup(): def _eintr_retry_call(func, *args): def call(*popenargs, **kwargs): def check_call(*popenargs, **kwargs): def check_output(*popenargs, **kwargs): def list2cmdline(seq): def getstatusoutput(cmd): def getoutput(cmd): def _demo_posix(): def _demo_windows(): _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
