ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()
Firstly I have a pandas series of recommended product (recmd_prdt_list). In this series there is a possibility of presence of deleted products. 650
So as to remove deleted products from the recommended products, I did the following :
recmd_prdt_list = user_lookup['Recommended items']
recmd_prdt_list
0 PLV08, PLPD04, PBC07, 555, PLF02, 963, PLF07, ...
1 123, 345, R922, Asus009, AIMAC, Th001, SAM S9,...
2 LGRFG, LG, 1025, COFMH, 8048, BY7, PLHL4, 569,...
3 COFMH, 5454, 8048, 1025, LG, len123, Th001, PL...
4 LGRFG, AIM-Pro, 569, Asus009, PLHL3, PL04, PLH...
5 PLV08, PLF09, PLF02, PBC04, PLF07, AIM-Pro, PL...
type(recmd_prdt_list)
pandas.core.series.Series
DataFrame of product status
product_status
ItemCode Status DeletedStatus
AIMAC 2 True
AIM-Pro 2 True
SAM S9 2 True
SH MV 2 True
COFMH 2 True
LGRFG 2 True
type(product_status)
pandas.core.frame.DataFrame
first_row = user_lookup['Recommended items'][0]
first_row
'PLV08, PLPD04, PBC07, 555, PLF02, 963, PLF07, HG8, jealous21, 4'
type(first_row)
str
Converting the str to list
first_row_list = list(first_row .split(","))
first_row_list
['PLV08', ' PLPD04', ' PBC07', ' 555', ' PLF02', ' 963', ' PLF07', ' HG8', ' jealous21', ' 4']
From the first row i took first itemcode to check the deleted status :
product_details = product_status.loc[product_status['ItemCode'] == 'PLV08']
product_details
ItemCode Status DeletedStatus
PLV08 2 False
type(product_details)
pandas.core.frame.DataFrame
product_details['DeletedStatus']
693 False
Name: DeletedStatus, dtype: bool
So as to check the deleted status of each product in the respective row and save to a new list. I wrote the following code :
itemcode = 'PLV08'
activ_product = []
if itemcode in product_status['ItemCode'].values:
print(itemcode)
product_details = product_status.loc[product_status['ItemCode'] == itemcode]
print(product_details)
if product_details['Status'] == 2 & product_details['DeletedStatus'] == 'False':
activ_product.append(itemcode)
Error :
PLV08
ClientId ItemCode Status DeletedStatus
499 2213 PLV08 2 False
