The need for this project became clear when Jason Morris came to the University of North Carolina at Chapel Hill to study Classics. Morris works at the Ancient World Mapping Center (AWMC), a foundation to advance the field of ancient studies with ...

The other day, a friend asked me a seemingly simple question: what's the best way to convert a list of integers into a string, presuming that the integers are ASCII values. For instance, the list [97, 98, 99] should be converted to the string 'abc'. Let's assume we want to write a function to do this. The first version I came ...

  • How To Submit to the Python Job Board

    How To Submit to the Python Job Board The Python Job Board is a free resource to help members of the Python community find paid work.

  • IDLE and tkinter with Tcl/Tk on macOS

    IDLE and tkinter with Tcl/Tk on macOS Important If you are using macOS 12 Monterey or later, you may see problems with file open and save dialogs when using IDLE or other tkinter-based applications.
