根据RFM分数细分客户并创建pandas DataFrame

Question

我已经对购买历史数据进行了RFM分析.

基于RFM类我已经对客户进行了细分，因为我的一些客户属于多个类别，我必须将客户细分为他们的所属类并添加到我的rfm表（添加单独的列'segment'）

CardNo新近度频率货币R_Quartile F_Quartile M_Quartile RFMClass Segment

我的rfmtable列看起来像上面不包括列'segment' - 我想添加到rfm表

到目前为止我所做的是

for card_no in rfmSegmentation['CardNo']:
>     for num in rfmSegmentation['RFMClass']:
>         num = str(num)
>         if int(num[0])==1 and int(num[1])==1 and int(num[2])==1:
>             print("RFM_class",num,"cardno",card_no,"Best Customer")
>         elif int(num[1])==1:
>             print("RFM_class",num,"cardno",card_no,"Loyal Customer")
>         elif int(num[2])==1:
>             print("RFM_class",num,"cardno",card_no,"Big Spender")
>         elif int(num[0])==3 and int(num[1])==1 and int(num[2])==1:  
>             print("RFM_class",num,"cardno",card_no,"Almost Lost")        
>         elif int(num[0])==4 and int(num[1])==1 and int(num[2])==1:   
>             print("RFM_class",num,"cardno",card_no,"Lost Customer")
>         elif int(num[0])==4 and int(num[1])==4 and int(num[2])==4:  
>             print("RFM_class",num,"cardno",card_no,"Lost Cheap Customer")

它打印每个客户的段，但我想将其添加为rfmtable中的单独列并将其转换为csv文件

任何帮助，将不胜感激
