This is a cron-task / scraper / Telegram bot I wrote to help me find an apartment in Berlin. In a nutshell, it checks a URL I supplied with my search criteria, and every time a new apartment was returned, I had the bot send me a message on Telegram so I could write immediately and be one of the first applicants. It almost definately does not work as-is. I was constantly having to change the code because of anti-robot stuff. But it can be used as an example.
It is a built with the Django web framework in Python programming language, and was deployed on Pythonanywhere, and I used pythonanywhere's scheduled tasks to check the site every few seconds.
I already had a telegram bot bc i use telegram bots for everything. You can read about how to make telegram bots here
