combining 2 dataframes pandas

df_3 = pd.concat([df_1, df_2])

pandas merge multiple dataframes

import pandas as pd
from functools import reduce

# compile the list of dataframes you want to merge
data_frames = [df1, df2, df3]
df_merged = reduce(lambda  left,right: pd.merge(left,right,on=['key_col'],
                                            how='outer'), data_frames)

merge two df

bigdata = pd.concat([data1, data2], ignore_index=True, sort=False)

combine dataframes

frames = [df1, df2, df3]
result = pd.concat(frames)

# sorted indices
