C# is more similar to Java than C++. Neither is very similar to C++, except in some cosmetic syntactic ways. Personally, that would be my last choice. C++ is the most portable of the three, and the only non- proprietary one (like Python). -- http://mail.python.org/mailman/listinfo/python-list

If you're targeting a specific job market, find out what is prevelant in that market. And keep in mind that if it's for a job, you'll also have to get up to speed on the relevant libraries and frameworks. If it's educational, I'd recommend C++ just to learn about pointers and memory management, so you get a better idea of what's going on under the covers in languages like Java and Python and Ruby and C#. -- http://mail.python.org/mailman/listinfo/python-list

Look at PyGame (http://pygame.org) and write a simple game, like asteroids or space invaders. Or heck, start with pong. You'll be amazed at how game programming will stretch your programming skills.

You missed the point completely. C++ has a new version coming out soon, and as part of it, the less attractive parts of the language (like C compatibility) are NOT being removed, as that would break a lot of existing apps. > People not willing to take the migration path (porting to 2.6, using > the -3 flag, refactoring and re-running the tests untill the warning > are gone, using the 2to3 tool...) will not upgrade.

If you want to upgrade to the next version of Python, you have to fix your code. That stinks.

You misunderstand. C++ has a lot of "warts" to maintain backwards compatibility with C. The standards committee could eliminate these warts to make the language "cleaner", but it would break a lot of systems. -- http://mail.python.org/mailman/listinfo/python-list

The existence of battery acid won't hurt me either, unless I come into contact with it. If one eventually upgrades to 3.0 -- which is ostensibly the desired path -- their code could break and require fixing. Backward compatibility is important. C++ could break all ties with C to "clean up" as well, but it would be a braindead move that would break existing code bases upon upgrade. -- http://mail.python.org/mailman/listinfo/python-list
