我正在尝试编写一个脚本来从 csvs 中清除信息。我有一个从 csv 创建的 pandas df,如下所示:
CUSTOMER ORDERS
hashed_customer firstname lastname email order_id status timestamp
0 eater 1_uuid 1_firstname 1_lastname 1_email 12345 OPTED_IN 2020-05-14 20:45:15
1 eater 2_uuid 2_firstname 2_lastname 2_email 23456 OPTED_IN 2020-05-14 20:29:22
2 eater 3_uuid 3_firstname 3_lastname 3_email 34567 OPTED_IN 2020-05-14 19:31:55
3 eater 4_uuid 4_firstname 4_lastname 4_email 45678 OPTED_IN 2020-05-14 17:49:27
4 eater 5_uuid 5_firstname 5_lastname 5_email 56789 OPTED_IN 2020-05-14 16:22:33
我有另一个 csv,其中包含我需要从该文件中清除的 hashed_customers。因此,如果此文件中的 hashed_customer 在 CUSTOMER ORDERS 中,我需要从行中删除名字、姓氏和电子邮件,同时保留其余部分,如下所示:
CUSTOMER ORDERS
hashed_customer firstname lastname email order_id status timestamp
0 eater 1_uuid NULL NULL NULL 12345 OPTED_IN 2020-05-14 20:45:15
1 eater 2_uuid 2_firstname 2_lastname 2_email 23456 OPTED_IN 2020-05-14 20:29:22
2 eater 3_uuid 3_firstname 3_lastname 3_email 34567 OPTED_IN 2020-05-14 19:31:55
3 eater 4_uuid NULL NULL NULL 45678 OPTED_IN 2020-05-14 17:49:27
4 eater 5_uuid 5_firstname 5_lastname 5_email 56789 OPTED_IN 2020-05-14 16:22:33
我当前的脚本如下所示:
print('FIND ORDERS FROM OPT-OUT CUSTOMERS')
cust_opt_out_order = []
for index, row in df_in.iterrows():
if row.hashed_eater_uuid in cust_opt_out_id:
cust_opt_out_order.append(row.order_id)
print('REMOVE OPT-OUT FROM OPT-IN FILE')
df_cust_out = df_in[~df_in['hashed_eater_uuid'].isin(cust_opt_out_id)]
但这是删除整行,现在我需要保留该行,只从该行中删除名称和电子邮件元素。如何使用熊猫从一行中删除元素?
