Thank you, Ned.

As I remember that I had opened a thread here last year, trying to use "2To3" tool to convert the ctypesgen package, but didn't success.

This time, somehow I find this "ctypesgen-python-3" package and can't wait to give it a try, but is disappointed again. I suppose there are many v3.x users who like to use ctypesgen to ease the using of ctypes. But obviously, it's not an easy work to do, convert 2 to 3:-)

By the way, does anyone know what the following codes does? (in printer.py file) and how to convert it to v3.x?

class WrapperPrinter:
    def __init__(self,outpath,options,data):
        ...
        ...
        self.print_header()
        print >>self.file
        
        self.print_preamble()
        print >>self.file

        self.print_loader()
        print >>self.file
        ...
        ...
