errrmmm it's a C while stmt with post-decrement; that's NOT the same as: for (; n; n--) ... If n is initially 3, the loop body is executed with n set to 2,1,0 and after exit n is -1. The nearest Python equivalents of "while (n--) func(n);" are (making the charitable assumption that initially n >= 0): ! while n: ! n -= 1 ! func(n) and ! for n in range(n-1, -1, -1): ! func(n) > > But unfortunately, no, I don't think there is an equivalent in python that > has the conciseness of the C statement.

The ability to write cryptic crap that you don't understand & that's so "powerful" that you can get into deep kaka really quickly? Hope you weren't writing software for embedded devices -- like heart pacemakers :-) -- http://mail.python.org/mailman/listinfo/python-list
