I don't understand what you are trying to do here. But regardless of your intention, the problem you have is nothing to do with updating os.environ. Proof: change the last line from this complicated expression: os.environ.update(line.partition('=')[::2] for line in output.split('\0')) to this simple expression: output.split('\0') and you will get the same error. os.environ is irrelevant. Your problem is only with Popen. What makes you think that Popen objects have a split() method? They are not documented as having this method: https://docs.python.org/2/library/subprocess.html https://docs.python.org/3/library/subprocess.html https://pymotw.com/2/subprocess/ -- Steven -- https://mail.python.org/mailman/listinfo/python-list
