Here we will use the requests library for getting the HTML Content from the Web URL.
# Get HTML Content
r = (“Enter Web URL:- “)
Step 3 (Parse HTML Content)

soup = BeautifulSoup(ntent, ”)
Step 4 (Fetch Dropdown option value)

In BeautifulSoup we will use the find() method for finding the select tag
Inside select tag, we will find all option tag using the find_all() method
Then we will Iterate through all option tags and get option value using text property.

options = nd_all(“option”)
