我有一个数据帧,并根据目标列(data['Retention Flag']=='Retained')
上的一个条件进行过滤,再次应用另一个条件,比如对每个列求和等于任何整数(这里是84)的值的数目
我有non_cat_column=['CONTRACT TERM', 'FINANCED AMOUNT', 'INTEREST RATE', 'EMI',.....etc]
我编写了一个工作正常的代码,通过条件过滤目标列,将列转换为dict,识别它们的值,以及对匹配项求和的循环。是否有其他更好的方法或容易获得的/语法
non_cat_column=['CONTRACT TERM', 'FINANCED AMOUNT', 'ACTIVATION DATE', 'CONTRACT END DATE', 'CONTRACT MATURITY DATE', 'INTEREST RATE', 'Ex Showroom', 'EMI']
for feature in non_cat_column:
print(feature)
print(data[feature][data['Retention Flag']=='Retained'].tail())
print('Values of each columns which have the Retention Flag as "Retained" in dictionary format')
print(data[feature][data['Retention Flag']=='Retained'].to_dict().values())
print('....the total number of 84 values in the feature column where Retention Flag=Retained.....')
print(sum(1 for value in (data[feature][data['Retention Flag']=='Retained'].to_dict().values()) if value==84))
输出:
CONTRACT TERM
13956 84
13957 60
13958 60
13959 24
13960 36
Name: CONTRACT TERM, dtype: int64
Values of each columns which have the Retention Flag as "Retained" in
dictionary format
dict_values([84, 60, 84, 84, 60, 84, 60, 48, 60, 84, 60, 84, 60. .... etc
])
.....the total number of 84 values in the feature column where Retention
Flag=Retained..... 172
