python3将csv文件中的两列数据读取出来，并且按行写入txt文本之中

import csv
import pandas as pd
a = open("taxi.csv", "r")
Hlength=len(a.readlines())
data_x= pd.read_csv(filepath_or_buffer = "taxi1.csv", sep = ",")["lo"].values
data_y= pd.read_csv(filepath_or_buffer = "taxi1.csv", sep = ",")["la"].values
f=open("jingweidu2.text", "w")
for i in range(0,Hlength):
    print(data_x[i],data_y[i])
    f.write(str(data_x[i]))
    f.write(" ")
    f.write(str(data_y[i]))
    f.write("
")
f.close()
