Group by consecutive index numbers

Question

I was wondering if there is a way to groupby consecutive index numbers and move the groups in different columns. Here is an example of the DataFrame I\'m using:

Answer 1

This is a groupby + pivot_table

---

m = df.index.to_series().diff().ne(1).cumsum()

(df.assign(key=df.groupby(m).cumcount())
    .pivot_table(index='key', columns=m, values=0))

                1             2
key
0    19218.965703  19279.216956
1    19247.621650  19330.087371
2    19232.651322  19304.316973
