I cannot remember where was it, but I saw a sentence in the Internet: "When programming, programmers spend more time for reading than writing". This is definitely true. We don't only read others' code but we also read our code again and again and again. Thus, a language which is easier to read can make the programmer very comfortable. I read many statements that "Python is a clean language". Now, I see what means "clean".
By the way, Python IDEs are so nice and powerful. I have downloaded Komodo and WingIDE and I've found them amazing! Of course, Lisp has also very good IDEs but even just these two Python IDEs can attract people to Python. Hmm, or shall I crack them? Gosh, no, no, this is illegal ;-) -- http://mail.python.org/mailman/listinfo/python-list
