我不知道如何实现这个,我在循环中考虑了 value_counts:
for name, month in zip(list(test_df["Client Name"].unique()), list(test_df["Month"])):
print(test_df[(test_df["Client Name"] == name) & (test_df["Month"] == month)].value_counts(["Payment Status"]))
最佳答案
关键是创建一个 bool 掩码:如果 Payment Status
是“Paid in full”,那么 True
否则 False
。现在您可以按 Client Id
、Month
和 Year
进行分组,以检查所有值是否都是 True
。使用 transform
将结果广播到组的每一行。最后,将 True/False
替换为其各自的值。
bool 掩码是通过向数据框添加新列 is_paid
动态创建的:
df['Qualification'] = (
df.assign(is_paid=df['Payment Status'] == 'Paid in Full')
.groupby(['Client Id', 'Month', 'Year'])['is_paid']
.transform('all').replace({True: 'Qualified', False: 'Not Qualified'})
)
print(df)
