使用 pandas 从数据框使用两个不同的列来选择行?

Q与此类似: 使用值列表选择行来自熊猫数据框

如果两列中的任何一个值都在列表中，我想进行数据框处理. 返回两列(组合结果#1和#4.

I want to dataframe if either value in two columns are in a list. Return both columns (combine results of #1 and #4.

import numpy as np
from pandas import *


d = {'one' : [1., 2., 3., 4] ,'two' : [5., 6., 7., 8.],'three' : [9., 16., 17., 18.]}

df = DataFrame(d)
print df

checkList = [1,7]

print df[df.one == 1 ]#1
print df[df.one == 7 ]#2
print df[df.two == 1 ]#3
print df[df.two == 7 ]#4

#print df[df.one == 1 or df.two ==7]
print df[df.one.isin(checkList)]
