Assume your main module has your exception hook code in it, up to and including the line "sys.excepthook = myexcepthook". As you have noticed, "1 = spam" in your main module would cause an uncaught exception. This is because this exception is raised during the compilation phase of the module, before you hooked the exception vector. This is true NO MATTER WHERE in the main module this statement is -- Python will compile the entire module before executing it. Now assume that the statement "1 = spam" is in module "foo.py" instead of in your main module. If you "import foo" at the top of your main module, you will have the same result but for slightly different reasons-- foo.py will be compiled during execution of the main module's "import" statement (although AFTER compilation of the main module), so the exception will still be raised before you have assigned your exception hook. HOWEVER, if you "import foo" AFTER the line "sys.excepthook = myexcepthook", then the compilation of foo.py will occur after your exception hook has been set, and your exception handler will execute on the syntax error "1 = spam" inside foo.py. So the bottom line is that you can't log syntax errors for your main module, but you _can_ log syntax errors for other modules which your main module imports. I think one of the reasons you are confused is that the interactive mode, by necessity, has to compile incrementally. But compilation of imported modules, and compilation of a main module in non-interactive mode, occurs before any code in that particular module is executed. Please let me know if it's still unclear.
