[Pythonedu-wg] Bit shift problem

[Carrie Anne Philbin]

Just to add to what Laura has said. This resource is part of a global
weather experiment. We have 1000 schools around the world taking part and
we want them to be able to program them with Python as well as with Java.
Helping with the conversion from 2 to 3 would impact a lot of young people!

Thanks,

Carrie Anne
