Answer 1

This is just a .melt, docs are here

In [33]: pd.melt(df.reset_index(),
                 id_vars=['values'],
                 value_vars=['interval1','interval2','interval3'])
Out[33]: 
  values   variable value
0    aaa  interval1   ##1
1    bbb  interval1   ##4
2    ccc  interval1   ##7
3    aaa  interval2   ##2
4    bbb  interval2   ##5
5    ccc  interval2   ##8
6    aaa  interval3   ##3
7    bbb  interval3   ##6
8    ccc  interval3   ##9
