In this pandas dataframe.append () example, we passed argument ignore_index = Ture. This helps to reorder the index of resulting dataframe. If ignore_index =False, the output dataframe’s index looks as shown below. Now, let us take two DataFrames with different columns and append the DataFrames.
What is a dummy dataset in pandas append?
