The sys module defines two hooks that are used in the interactive interpreter:
* sys.displayhook(value) gets called with the result of evaluating the line when you press ENTER; * sys.excepthook(type, value, traceback) gets called with the details of the exception when your line raises an exception. Is there a way to hook into the interactive interpreter *before* it is evaluated? That is, if I type "len([])" at the prompt and hit ENTER, I want a hook that runs before len([]) is evaluated to 0, so that I get the string "len([])". -- Steven -- http://mail.python.org/mailman/listinfo/python-list
