df1 = pd.DataFrame.from_items([('A', [1, 2, 3]), ('B', [4, 5, 6])])
df2 = pd.DataFrame.from_items([('B', [5, 6, 7]), ('A', [8, 9, 10])])
df3 = pd.DataFrame.from_items([('C', [5, 6, 7]), ('D', [8, 9, 10]), ('A',[1,2,3]), ('B',[4,5,7])])
df_list = [df1,df2,df3[['A','B']]]
pd.concat(df_list, ignore_index=True)
