This is regarding the Python drop-down list response.
I would like to create a GUI that has a drop down list containing the data and displayed based on the stats of the list contents. I am interested in using Tkinter, wxPython or PyGTK. My data is coming from a csv file. I am using Python 2.79 and have Windows 8 as an operating system Thank you, > From: tutor-requ...@python.org > Subject: Tutor Digest, Vol 130, Issue 47 > To: tutor@python.org > Date: Wed, 31 Dec 2014 20:00:28 +0100 > > Send Tutor mailing list submissions to > tutor@python.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://mail.python.org/mailman/listinfo/tutor > or, via email, send a message with subject or body 'help' to > tutor-requ...@python.org > > You can reach the person managing the list at > tutor-ow...@python.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Tutor digest..." > > > Today's Topics: > > 1.
