Hi, Can anyone enlighten me to the search path mechanism in ctypes' LoadLibrary? I have a DLL that resides elsewhere that is not in any default search path. I tried adding the path to `sys.path` before attempting to load said DLL but I still get "WindowsError: [Error 126] The specified module coul

You can make it a required input with default values to sys.argv when you start the program. Parse the content of the file given by sys.argv, then cache it in some global module or pass it around as arguments... That said, if you still want to go the route of knowing where the current directory of

GUI application is a whole other matter entirely. For that, you might want to look into cross-platform GUI toolkits with Python bindings. E.g., PyQT [1], wxPython [2], TkInter [3], etc. Python, after all, is just a cross-platform language. To do all those user-friendly bells and whistles, you'd nee

Django is excellent as a CMS builder (think blogs, articles websites), though it has many uses beyond that, as well.

As a general rule, I group all my imports in the beginning of the module's source, even if it is only used a handful of times by a few functions. However, on such cases as the import is only needed by specific function(s) zero or once, then I do the import in the function itself. Importing argpars
