exception raised by nested iterator being ignored by for loop

I'm writing a wrapper class to handle the line merging and filtering for a log file analysis app The problem I'm running into is that the StopIteration exception raised when the wrapped file goes past EOF isn't causing the second for loop to stop. Wrapping the second for loop in a try/except claus

Re: Can a function access its own name?

Delays getting data on sys.stdin.readline() ?

Hello, I've got a program that (ideally) perpetually monitors sys.stdin for lines of text. As soon as a line comes in, my program takes some action. The problem is, it seems like a very large amount of data must accumulate on sys.stdin before even my first invocation of readline() returns. This
