You didn't edit the following line to include the name of your .env file. I used the name virus_total.env

# load_dotenv will look for a .env file and if it finds one it will load the environment variables from it
load_dotenv("virus_total.env")

"""
/////  IMPORTANT  /////
ADD .env to gitignore to keep it from being sent to github
and exposing your API key in the repository
"""

In this .env file, you need a line as follows (as an example only):

API_KEY1="5da36e3aa622a8b6d81dd168334ef12379bdad4d1fa7f11ce3f75829ccc5e9ac"

You get this api key from your account on the virus total website.

Then, you will get the following result

python vt-ip-url-analysis.py -s google.com
