                  问题描述

                  I have a pandas data frame that looks something like this:

                    A B C
                  0 1 2 3
                  1 4 5 6
                  2 7 8 9
                  

                  And I would like to add row 0 to the end of the data frame and to get a new data frame that looks like this:

                    A B C
                  0 1 2 3
                  1 4 5 6
                  2 7 8 9
                  3 1 2 3
                  

                  What can I do in pandas to do this?

                  解决方案

                  You can try:

                  df = df.append(df.iloc[0], ignore_index=True)
