Your shell variable "esc" is 4 characters long. Your Python program prints those four characters. You want it to re-interpret those 4 characters into a single escape character. One of this group's regular participants can (I hope) tell us three breathtakingly elegant ways to do that. I'm sorry I can't. When you run echo, it recognizes the 4-character "esc" as a convention for representing a single character, and performs the re-interpretation for you. When you tell python "print '\033[30;44m foo \033[0m'", python interprets the "\033" as a single character. -- To email me, substitute nowhere->spamcop, invalid->net. -- http://mail.python.org/mailman/listinfo/python-list
