最近写了一个12306查票的Python程序，在调试过程中遇到name not defined的bug，这个程序在Python3.6版本下是可以正常运行的，今天在Python2.7环境下运行一直提示这个，希望得到一个解决办法

程序如下：

macbookpro:bin miyamoto$ ./python -V
Python 2.7.10

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import requests
import json   
from PIL import Image
import getpass
import re
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
from urllib3.exceptions import InsecureRequestWarning



if __name__ == '__main__':
    url = 'https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version'  # 根据查看源码查出来的
    response = requests.get(url, verify=False)
    print response.text
    stations = re.findall('([a-z]+)\|([\u4e00-\u9fa5]+\|[A-Z]+)', response.text)  # 用正则表达式 来获取车站的拼音和大小写字母的代号信息
    print stations
    stszm = re.findall('[\u4e00-\u9fa5]+\|[A-Z]+', response.text)  # 用正则表达式 来获取车站的拼音和大小写字母的代号信息
    
    # start_input = input("请输入始发站:\n")
    # stopt_input = input("请输入终点站:\n")
    # tripDate = input("请输入日志[YYYY-mm-dd]:\n")
    start_input="北京西"
    stopt_input="石家庄"
    tripDate="2018-09-30"
    for startAndStopStation in stations:
        if startAndStopStation[1] == str(start_input):
            startStation = start_input
        elif startAndStopStation[1] == str(stopt_input):
            stopStation = stopt_input
    for stationsSuoxie in stszm:
        if str(stationsSuoxie).split('|')[0] == start_input:
           startStationSuoxie = str(stationsSuoxie).split('|')[1]
           print startStationSuoxie
        elif str(stationsSuoxie).split('|')[0] == stopt_input:
            stopStationSuoxie = str(stationsSuoxie).split('|')[1]
            print stopStationSuoxie
            # print str(stationsSuoxie).split('|')[0]

    adult = "https://kyfw.12306.cn/otn/leftTicket/queryA?leftTicketDTO.train_date=%s&leftTicketDTO.from_station=%s&leftTicketDTO.to_station=%s&purpose_codes=ADULT" %(tripDate,startStationSuoxie,stopStationSuoxie)
    # ticketlist=requests.request('get',adult).text

    print adult

结果最后调试一直报错，语法方面和逻辑方面没有错误。求解！

Traceback (most recent call last):
  File "/Users/miyamoto/Documents/PycharmProject/12306.py", line 191, in <module>
    adult = "https://kyfw.12306.cn/otn/leftTicket/queryA?leftTicketDTO.train_date=%s&leftTicketDTO.from_station=%s&leftTicketDTO.to_station=%s&purpose_codes=ADULT" %(tripDate,startStationSuoxie,stopStationSuoxie)
NameError: name 'startStationSuoxie' is not defined

另外再付一个bug

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import json   
from PIL import Image
import requests
import getpass
import re

from urllib3.exceptions import InsecureRequestWarning

requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
if __name__ == '__main__':

    url = 'https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version'  # 根据查看源码查出来的
    
    # response=urllib2.urlopen(url)
    # print response.read()
    response = requests.get(url, verify=False)
    stations = re.findall("([a-z]+)\|([\u4e00-\u9fa5]+))", response.text) 
    print stations

上面这个代码运行出来后显示为空字典,求解。

/Users/miyamoto/Documents/PycharmProject/python3/bin/python /Users/miyamoto/Documents/PycharmProject/12306_new.py
[]

另外在python2.7.10下单独使用re.findall()进行正则匹配respone.text，没有任何信息；在python3.6以上的环境下进行匹配就会有信息展示，下面是python3.7的结果(中文前面的车站缩写我没有添加)：

['北京北', '北京东', '北京', '北京南', '北京西', '广州南', '重庆北']
