Actually not related at all. Nothing like lambda or iter exist in C++. They are a bit complicated to explain to newbies (unless you've programmed in Lisp or in functional-programming languages), thus the suggestion of looking in the docs. That's also the reason that suggesting using lambda and iter that way was considered a bad answer to "how do you write something like 'while c = f.read(1)'". Anyway, quick explanation of lambda: it's a way of creating functions without having to give then names. Example: lambda x: x*x is a function that computes the square of x. So you could say n = (lambda x: x*x)(3) which sets n = 9. There is a faction on clpy which says lambda is bad and all functions should have their own names. Others say they're useful for things like callbacks, and requiring all functions to be named makes no more sense than requiring all intermediate results in infix expressions to be named. You unfortunately happened to trip into a slightly contentious topic on clpy and got flamed a bit as a result. I won't explain iter here, since it's more complex than lambda. -- http://mail.python.org/mailman/listinfo/python-list
