I used to refer to other people's code and made a 12306 command-line train ticket query tool in Python. It's very interesting! So I made a similar - Ctrip ticket finder.

The effect of Ctrip's official website query is as follows:

The effect of Python command line interface query is as follows:

Enter the departure, destination and boarding date to see the optional flight, airport, departure and arrival time, ticket price and other information.

The source code of the program is as follows:

1.air_stations.py

2.airline_ticket.py

 9 response = requests.get(url,verify=False)
10 station = re.findall(u'([\u4e00-\u9fa5]+)\(([A-Z]+)\)', response.text)
11 stations = dict(station)
12 pprint(stations,indent = 4)

In fact, this small program can also be expanded, such as saving the query records to the local computer (in the format of txt, or in the database) or more powerful, you can also set the timing of automatic query; you can also set the query to automatically send email reminders; you can also use the Python GUI library to make this program into the form of desktop software....
