I am a computer scientist with over 30 years of experience writing software and training, mentoring, and supporting software developers in advanced technologies. IDE's have always been a particular interest of mine; I've used many and with many languages over many years. Most of them are little more than demoware — awkward to use, ugly, and lacking support for many of a developer's routine actions.
The Wing IDE for Python gets it right. It is well-designed, attractive, flexible, and full-featured. It includes an editor, browsers, inspectors, a debugger, good documentation, etc. — all the facilities a Python developer needs. The arrangement, keybindings, and behavior of these facilities are quite configurable. The X11-based Mac implementation of this cross-platform application is nicely done, fitting comfortably within both the Unix and OS-X sides of the Mac environment.
This is a serious large-scale application whose price is justified by the richness and usability of the facilities it provides. It works well, looks good, and gives the Python developer everything needed to work effectively. Buy it.
