从groupby创建Pandas数据帧

Question

我有以下groupby语句;

test1_df = pd.DataFrame(cust_merge_df.groupby(['customer_org', 'reseller']).size())

返回以下内容：

print(test1_df)
                                                                    0
customer_org                     reseller                           
cust1                            reseller 1                       26
cust2                            reseller 2                        1
cust3                            reseller 3                       14

我需要做的是将数据拆分为3列，其中 customer_org 和经销商是列标题;

customer_org                     reseller                        total  
cust1                            reseller 1                       26
cust2                            reseller 2                        1
cust3                            reseller 3                       14

我测试了建议@ create a new data frame from GroupBy object in pandas但没有成功。
