Message-ID: <1308120179.1952.50.camel@wolfrage-LE1600> Content-Type: text/plain; charset="UTF-8" Unfortunately I am not able to inherit "stdscr" using that method. As Python returns with an error stating that "stdscr" is not defined. This error is returned at run time and by the compiler prior to actual execution. If you would like I can write a quick example that will generate the error message for that method. -- Jordan On Wed, 2011-06-15 at 02:04 -0400, Japhy Bartlett wrote: > When you're subclassing something, you use the syntax: > > class Foo(Bar): > > It seems like you're trying to do: > > class Bar: > class Foo: > > - Japhy > > On Wed, Jun 15, 2011 at 12:47 AM, WolfRage <[email protected]> wrote: > > I can not get this to behave in the manor that I would like.

There are a couple of EBCDIC codecs (see list of codecs in http://docs.python.org/library/codecs.html). Try: open('file.txt').read().decode('ibm500').encode('ascii','replace') You'll get '?' for chars ascii doesn't support. -Mark ------------------------------ _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor End of Tutor Digest, Vol 88, Issue 54 ************************************* _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
