如何取2个参数并应用函数

Question

我有一个数据帧需要在uid\u has\u new和uid\u hash上创建模糊比率/hamming距离并创建一个新表

 uid    uid_hash  uid_hash_new
1   123 ABC28071  ABC28079
4   121 ABC28071  ABC28089

伪代码

import pandas as pd
def ratio(x,y):
    return
df['ratio'] = df['uid_hash_new','uid_hash'].apply(ratio)

Answer 1

你可以做：

def ratio(a):
    return a[0]+a[1]

df['ratio'] = df['uid_hash_new','uid_hash'].apply(ratio, axis=1)

所以a[0]将是uid_hash_new（x）和a[1]：uid_hash（y）

Answer 2

将^{}与lambda函数一起使用：

df['ratio'] = df.apply(lambda x: ratio(x['uid_hash_new'], x['uid_hash']), axis=1)
