Thanks for your contribution but I suggest that:
In Q-13:
Top15['PopEst'] = Top15['PopEst'].apply(lambda x: "{:,}".format(x))
this will adding commas "," to thousands
in Q-12:
x = Top15.groupby(['Continent','bins']).size()
x.index.names = ['Continent', '% Renewable']
and this will satisfy the index naming requirement of Q-12
