python使用pandas两数组相加

Question

版本：python3.6、anaconda3(64bit)

问题描述：

A=df['b2'].values.tolist()
B=df['sex'].values.tolist()
print(A)

['0.253', '0.366', '0.363',]
print(B)
['45.64', '75.54', '2.15',]

如何将两个数组对应相加，形成新的数组C

请大神指点，谢谢

Answer 1

 def my_test(a, b):
    return float(a) + float(b)


def test():
    a=['0.253', '0.366', '0.363',]
    b=['45.64', '75.54', '2.15',]
    data={'a':a,'b':b}
    df=pd.DataFrame(data)
    print(df)
    df['Value'] = df.apply(lambda row: my_test(row['a'], row['b']), axis=1)
    print(df)
test()
