Swapping rows within the same pandas dataframe

Question

I\'m trying to swap the rows within the same DataFrame in pandas.

I\'ve tried running

a = pd.DataFrame(data = [[1,2],[3,4]], index=range(2), columns          


        

Answer 1

The accepted answer does not make changes the index name.

If you only want to alter the order of rows you should use dataframe.reindex(arraylike). Notice that the index has changed.
