熊猫，与数据框行条目的args一起应用

我认为您需要：

import pandas as pddf = pd.Dataframe({'A':[1,2,3],        'B':[4,5,6]})print (df)   A  B0  1  41  2  52  3  6def myfunction(B, A):    #some staff      result = B + A     # do something here to get the result    return resultdf['C'] = df.apply(lambda x: myfunction(x.B, x.A), axis=1)print (df)   A  B  C0  1  4  51  2  5  72  3  6  9

要么：

def myfunction(x):    result = x.B + x.A    # do something here to get the result    return resultdf['C'] = df.apply(myfunction, axis=1)print (df)   A  B  C0  1  4  51  2  5  72  3  6  9
