歡迎隨時回家——python制作一個火車票搶票版本（附完整代碼，僅供學習參考）

嗨害大家好鴨~我是小熊貓

今天教大家用Python制作一個12306查票程序腳本（僅供學習參考）

有什麼python相關報錯解答自己不會的、或者源碼資料/模塊安裝/女裝大佬精通技巧 都可以來這裡：（https://jq.qq.com/?_wv=1027&k=2Q3YTfym）或者+V：python10010問我（文末就有）

首先，先導入本次所需的模塊

import requests
import pandas as pd
import json

請求數據

找到數據來源

url = 'https://kyfw.12306.cn/otn/leftTicket/query'
data = {

'leftTicketDTO.train_date': train_date,
'leftTicketDTO.from_station': city_json[from_station],
'leftTicketDTO.to_station': city_json[to_station],
'purpose_codes': 'ADULT',
}
headers = {

'Cookie': '_uab_collina=163108019860709243490927; JSESSIONID=3A879F34238B594124705B10D7C0B0E6; BIGipServerotn=3956736266.64545.0000; guidesStatus=off; highContrastMode=defaltMode; cursorStatus=off; BIGipServerpassport=870842634.50215.0000; RAIL_EXPIRATION=1631354049020; RAIL_DEVICEID=jY49UGp1PWZZ0cY6CWj2wmKFDH60qsPXbu7L4D2DjNDJSM4sbqZmmlUm62-6L3k9SNtBAUgBPn7Rh1-FAxka97-nHNpT3QIh5YIXtw3mGao0mjLNkIv2ayvwqxWyFhdbos5_ziUA3XVil7awDZ0EjzKBAWdl22Hu; route=495c805987d0f5c8c84b14f60212447d; _jc_save_fromStation=%u957F%u6C99%2CCSQ; _jc_save_fromDate=2021-09-08; _jc_save_toDate=2021-09-08; _jc_save_wfdc_flag=dc; _jc_save_toStation=%u5CB3%u9633%u4E1C%2CYIQ',

}
response = requests.get(url=url, params=data, headers=headers)

自動識別編碼

response.encoding = response.apparent_encoding

數據解析取值

 for index in result:
# requests.utils.unquote(index)
index_list = index.replace('有', 'Yes').replace('無', 'No').split('|')
# print(index_list)
train_number = index_list[3] # 車次
if 'G' in train_number:
time_1 = index_list[8] # 出發時間
time_2 = index_list[9] # 到達時間
prince_seat = index_list[32] # 特等座
first_class_seat = index_list[31] # 一等座
second_class = index_list[30] # 二等座
dit = {

'Num': train_number,
'Start': time_1,
'End': time_2,
'Top': prince_seat,
'First': prince_seat,
'Second': second_class,
'Yz': '-',
'Wz': '-',
'Rw': '-',
'Yw': '-',
}
else:
time_1 = index_list[8] # 出發時間
time_2 = index_list[9] # 到達時間
hard_seat = index_list[29] # 硬座
no_seat = index_list[26] # 無座
soft_sleeper = index_list[23] # 軟臥
hard_sleeper = index_list[28] # 硬臥
dit = {

'Num': train_number,
'Start': time_1,
'End': time_2,
'Top': '-',
'First': '-',
'Second': '-',
'Yz': hard_seat,
'Wz': no_seat,
'Rw': soft_sleeper,
'Yw': hard_sleeper,
}
lis.append(dit)
content = pd.DataFrame(lis)
print(content)

實現查詢一座城市車次數據

實現全國車次查詢

f = open('city.json', mode='r', encoding='utf-8')
text = f.read()
city_json = json.loads(text)
while True:
from_station = input('請輸入你出發的城市： ')
to_station = input('請輸入你達到的城市： ')
train_date = input('請輸入乘車時間(2021-09-08/年-月-日)：')

再次查詢/退出

again = input('是否繼續查詢(Y/N): ')
if again == 'Y' or again == 'y':
continue
else:
break
