I think this holds true for experienced programmers, who often report a difficult unlearning process with Lisp. However, for people without preconceptions, the difference is likely less -- after all, many have painful memories of poorly-taught math and computer classes in school. So Python's similarity to gradeschool math may not be such a plus. Richard Stallman explained about a Lisp variant: "Multics Emacs proved to be a great success -- programming new editing commands was so convenient that even the secretaries in his office started learning how to use it. They used a manual someone had written which showed how to extend Emacs, but didn't say it was a programming. So the secretaries, who believed they couldn't do programming, weren't scared off. They read the manual, discovered they could do useful things and they learned to program." <http://www.gnu.org/gnu/rms-lisp.html> But of course this is anecdotal evidence. > Consider this: Lisp has had years of development, it has had millions of > dollars thrown at it by VC firms -- and yet Python is winning over Lisp > programmers. Think about it. Even now, Lisp still contains radical concepts (as in latin's radix meaning "root"), and overly radical ideas tend not to dominate in the marketplace. So we see an incremental progression towards Lisp ideas. Guy Steele, a central figure in Java, claimed: "And you're right: we were not out to win over the Lisp programmers; we were after the C++ programmers. We managed to drag a lot of them about halfway to Lisp. Aren't you happy?" <http://people.csail.mit.edu/gregs/ll1-discuss-archive-html/msg04045.html> But speaking of the marketplace, there's at least one Lisp company sustaining itself by asking for a cut of its customers' revenues... The last Lisp implementation I used "merely" asked for thousands per head per platform. ;) (Personally, I used Python before being aware of Lisp. Now I use Common Lisp all the time, though I will recommend Python when I consider it more appropriate. A few months ago, I missed the Condition System most when using Python, and also lexical scope. However, it is nice to work with friends, who know Python and not Lisp.) Tayssir -- http://mail.python.org/mailman/listinfo/python-list
