Hi Kondal&nbsp;,<br /><br />I agree the coding guidelines and tools can help improve the python code quality, but I think these guidelines in this spec are too general for BaseTools. Besides the coding style,&nbsp; BaseTools has many specific code issues, such as the high coupling between modules, not clear module interface, big function with hundreds lines, abused global variables. I hope there could be a python code design guidelines, for example, how to apply the software design principle or the software design pattern in the Basetools development process.<br /><br />I think this spec itself looks good.<br /><br />Thanks,<br />Bob
