How do I combine two dataframes?

Use pd.concat to join multiple dataframes:

df_merged = pd.concat([df1, df2], ignore_index=True, sort=False)

DEPRECATED: DataFrame.append and Series.append were deprecated in v1.4.0.

Use append:

df_merged = df1.append(df2, ignore_index=True)

And to keep their indexes, set ignore_index=False.
