def Family_feature(df):
df['Fam_Size'] =df['SibSp']+df['Parch']
df['Fam_Size'].loc[df['Fam_Size'] == 0] = 1
df['Fam_Size'].loc[(df['Fam_Size'] > 1) & (df['Fam_Size'] <= 3)] = 2
# df['Fam_Size'].loc[df['Fam_Size'] == 2] = 2
# df['Fam_Size'].loc[df['Fam_Size'] == 3] = 2
df['Fam_Size'].loc[df['Fam_Size'] > 3] = 3
return df
|
df['Fam_Size'].loc[(df['Fam_Size'] > 1) & (df['Fam_Size'] <= 3)] = 2 只要中间加一个 & 符号 ， 然后把两边的condition括号起来就行。
以上这篇对pandas里的loc并列条件索引的实例讲解就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
