获取file中字段，写入到TXT文件中

一下代码省略了很多，哈哈哈

a.txt文件

uid,type,pointx,pointy,name
1,9,911233763,543857286,区间测速起点
3,9,906371086,545335469,区间测速起点

........

省略千万行数据，哈哈哈

代码

#!/usr/bin/python
# encoding: UTF-8

with open(r"D:\work\a.txt", "r") as f:
    f.readline()
    i = 0
    for line in f:

        uid, type, pointx, pointy, name= line.split(",")

        if name == "区间测速起点":
            i = i + 1

            f1 = open('latlon_value1.txt', 'a+')
            f1.write(pointx, pointy)
            f1.close()

            print i, "%s" % name
。。。。。。。
    
省略千百行代码，哈哈哈

f.close
