Answer 1

If your pie chart is coming out with grouped chunks of the same colour when utilising the solution above, try changing the colour map from 'Set1' to any map you like from the following link: https://matplotlib.org/examples/color/colormaps_reference.html

As for randomising the colours, I suggest that you randomise the cs array in the solution above. But that doesn't really give a nice spectrum of colours.
