I actually rejected it because I thought it would be extremely boring after a few days, I did that for a couple of projects when I was writing desktop apps in Python 2.x and I found it very easy (2.7 to 3.x is not especially hard either in most cases).

I never understood the point of hiring a full team for at least 6 months just for that. The only explanation I can find is that the project manager was clueless about Python.
