Hi all, I was perusing the standard library, and was wondering if anyone knew how the internals of Python work, roughly or no. Basically, I assume os.pipe() resides in a DLL somewhere, yet when I open up Python24.DLL in PEexplorer I can't find mention of pipes anywhere... am I looking the right

In your code that line is not executed. And if it was at some stage, it will give you an error. max_item is a list and you cannot put a string and a list together: "TypeError: cannot concatenate 'str' and 'list' objects". What are trying to do with this line? 'maximum = 0' and so product will
