如下所示：

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 只要中間加一個(gè) & 符號(hào) ， 然后把兩邊的condition括號(hào)起來就行。

以上這篇對(duì)pandas里的loc并列條件索引的實(shí)例講解就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持武林站長站。
