任务： 合生元品牌的奶粉会员的营养品子品和其他大类的购物篮分析
思路：
合生元奶粉流水与营养品二级品类流水 依据流水号left join, 再与其他大类流水left join,且大类的类别名称要更改
获得合生元奶粉(品类cls)和 营养品二级品类(品类cls2)流水，并left join
zhenjia= saleflow.item_name.str.contains('奶粉')|saleflow.item_brandname.str.contains('奶粉')|saleflow.cls.str.contains('奶粉')|saleflow.cls2.str.contains('奶粉')&saleflow.c1.str.contains('奶粉')&saleflow.c2.str.contains('奶粉')|saleflow.c3.str.contains('奶粉')naifen_saleflow=saleflow[zhenjia]naifen_saleflow['品牌'] = naifen_saleflow.apply(pinpai_class_pro,axis=1) # 这些函数只能针对奶粉数据naifen_vipflow =naifen_saleflow[(naifen_saleflow['card_id']!=np.nan) & (naifen_saleflow['custype']=='vip')&(naifen_saleflow['sale_money']>0)]yyp_saleflow= saleflow[saleflow['cls']=='营养品']#saleflow_naifen_hsy = saleflow_naifen[saleflow_naifen['品牌']=='合生元']YYP =yyp_saleflow[[ 'branch_no','card_id','flow_no','cls2', 'shopid_cardid','age']]saleflow_heshengyuan_naifen = naifen_saleflow[naifen_saleflow['品牌']=='合生元']HSY_NAIFEN=saleflow_heshengyuan_naifen[[ 'shopId','branch_no', 'card_id','flow_no', 'cls', 'shopid_cardid']]
合生元奶粉和营养品左连接
HSY_NAIFEN_YSJ = HSY_NAIFEN.merge(YYP, how='left')
再获得各大类（cls 中的用品、玩具、辅食等）的流水，并且各大类的里面要重命名，比如 用品的 cls 列名要重命名为 cls_yongpin, 依次类推
yongpin_saleflow= saleflow[saleflow['cls']=='用品']YONGPING =yongpin_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_yongpin'})zhipin_saleflow= saleflow[saleflow['cls']=='纸品']ZHIPIN =zhipin_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_zhipin'})wanju_saleflow= saleflow[saleflow['cls']=='玩具']WANJU =wanju_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_wanju'})mianpin_saleflow= saleflow[saleflow['cls']=='棉品']MIANPIN = mianpin_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_mianpin'})fushi_saleflow= saleflow[saleflow['cls']=='辅食']FUSHI = fushi_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_fushi'})fuwu_saleflow= saleflow[saleflow['cls']=='服务']FUWU = fuwu_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_fuwu'})chechuang_saleflow= saleflow[saleflow['cls']=='车床']CHECHUANG = fushi_saleflow[[ 'branch_no','card_id','flow_no','cls', 'shopid_cardid','age']].\rename(columns={'cls':'cls_chechuang'})
最后合并
RESUT =(((((HSY_NAIFEN_YSJ.merge(YONGPIN,how='left')).merge(ZHIPIN,how='left'))\ .merge(MIANPIN,how='left')).merge(FUSHI,how='left')).merge(FUWU,how='left')).\merge(CHECHUANG,how='left').merge(WANJU,how='left')
连接各类别字符串，得到订单购物篮
RESULT =RESUT.replace(np.nan,'')RESULT['订单购物篮']= RESULT['cls']+'-'+RESULT['cls2']+'-'+RESULT['cls_zhipin'] + \'-'+ RESULT['cls_fuwu'] + '-'+ RESULT['cls_mianpin']+'-'+\RESULT['cls_chechuang']+'-'+RESULT['cls_yongpin']+'-'+ RESULT['cls_wanju'] +'-'+ RESULT['cls_fushi']
