Question

我使用上面链接中的poverty.txt文件在python中构建线性回归。当我尝试使用panda导入文件时，我在列之间获得了更多空格。因此，我无法获取所需列的正确结果。我使用以下代码

from numpy import arange,array,ones#,random,linalg
from pylab import plot,show
from scipy import stats
import numpy as np
import pandas as pd


data = pd.read_csv('poverty.txt',delimiter='\t')
print "data=",data

print data[['Location','PovPct']]

打印数据时，我得到以下输出：

Answer 1

import pandas as pd
data = pd.read_csv("poverty.txt", delim_whitespace=True)
data
