He needs it 6 column 6 that 's ok , But it was only given 6 column 3 that 's ok .
In general, look at your own creation dataframe Is there any mistake
pdd_annual_transaction_value = pd.DataFrame([[pdd_201701_201712[0],
pdd_201704_201803[0], pdd_201707_201806[0], pdd_201710_201809[0],
pdd_201801_201812[0], pdd_201804_201903[0]], [pdd_201701_201712[1],

Found that he needed six lines , And I wrote it wrong , It should be changed to
pdd = pd.DataFrame([[pdd_201701_201712[0], pdd_201701_201712[1],
pdd_201701_201712[2]], [pdd_201704_201803[0], pdd_201704_201803[1],
pdd_201704_201803[2]], [pdd_201707_201806[0], pdd_201707_201806[1],
pdd_201707_201806[2]], [pdd_201710_201809[0], pdd_201710_201809[1],
