The script makes a GET request to the URL using the requests library, and retrieves the HTML content of the website. The content is then passed to BeautifulSoup for parsing.
The content variable is then used to search for the 'div' tag with class "gdlr-core-pbf-column gdlr-core-column-60 gdlr-core-column-first". This is done using the find() method, which returns the first occurrence of the tag.
The script then finds all the 'h3' tags with class "gdlr-core-blog-title gdlr-core-skin-title". These tags contain the titles of the notices on the notice board.
A for loop is used to iterate over the titles and extract the text content of each title. The text content is then stripped of any whitespaces and is stored in the 'notices' variable.
Finally, the script opens a file named "notice.txt" and appends the notices to the file using the "write" method. The file is then closed using the close() method. The notices are also printed to the console for easy viewing.
