您可以使用numpy select()

You can use the numpy select()

import pandas as pd 
import numpy as np



condition = [(df.column1==1) & (df.column2==1) & (df.column3==1) & (df.column4==1)]
choices = [1]
df['output'] =np.select(condition, choices, default= 0)

如果您有多列，则可以使用np.apply_along_axis()

if you have multiple columns you can use the np.apply_along_axis()

def ex(x):
    a = 0
    if x.all() == 1.0:
        a = 1
    return a

df['output'] = np.apply_along_axis(ex,1,df)
