Grabbing with Python and Grab framework


The program uses one of the sites of the Russian court site as a source of data, in code, at https://vytegorsky--vld.sudrf.ru.
It searches for the specified words in the list of assigned cases from the current day to the appointed day and sends the search result to the e-mail.

In the search_list list, the words that will be searched are assigned.
The number of days viewed, starting from the current, in which the search will occur is set DaysFuture variable.
The settings for the SMTP server and the sender and recipient mailboxes are also set. The process of running the logged code in the example_app.log file.

# Search for character lines on the court's website in the 
#   section "To-do List" of the hearing days:
#   - with the sending of search results to email;
#   - with the logging of the execution process.
