python - 合并 Pandas 中的几个数据透视表

Question

如何合并两个 pandas 数据透视表？当我尝试运行我的代码时出现错误:keyerror

data_pivot= pandas.DataFrame(data.pivot_table(values = 'NR_ACTIONS', index=["HOUR", "OPID", "NAME"], columns='CONTACTED_PERSON_NEW', aggfunc='sum'))
data_pivot.fillna(0, inplace=True)
data2_pivot= pandas.DataFrame(data2.pivot_table(values = 'AMOUNT_PA', index=["HOUR", "OPID", "NAME"], columns='PA_TYPE', aggfunc='sum'))
data2_pivot.fillna(0, inplace=True)
all_data = pandas.merge(data_pivot, data2_pivot, 'left', on = ["HOUR", "OPID", "NAME"] ) 

Answer 1

我的问题的答案是:

data_pivot= pandas.DataFrame(data.pivot_table(values = 'NR_ACTIONS', index=["HOUR", "OPID", "NAME"], columns='CONTACTED_PERSON_NEW', aggfunc='sum'))
data_pivot.fillna(0, inplace=True)
data_pivot.reset_index( inplace=True)
data2_pivot= pandas.DataFrame(data2.pivot_table(values = 'AMOUNT_PA', index=["HOUR", "OPID", "NAME"], columns='PA_TYPE', aggfunc='sum'))
data2_pivot.fillna(0, inplace=True)
data2_pivot.reset_index( inplace=True)
all_data = pandas.merge(data_pivot, data2_pivot, 'left', on = ["HOUR", "OPID", "NAME"] )
