The problem with 2to3 is that the results are Python 3 only. The tool python-modernize <https://python-modernize.readthedocs.io/en/latest/> does a little better and its results will run under 2 or 3, but they will also depend on the library 'six'.
Drivers and uploaders are especially tricky because they have to do string <--> byte conversions. Those almost always have to be hand coded. In the end, I've found it easiest just to grind through the code manually. -tk On Wed, May 6, 2020 at 4:17 PM Greg from Oz <ubeau...@gmail.com> wrote: > I have run a program called 2to3 python
