A small python code can allow us to track any single tag in a web. It’s usefull for amazon, also for others kind of shops that haven’t a tracker yet.
Instructions for using
First, type on the terminal:
chcp 65001
That’s for character encoding. More info here
Then, install bs4 and html5lib:
conda install bs4
conda install html5lib
Second step: google “my user agent” and add the line in the header asignation below.
Third, add this in an empty python file and save as price_tracker.py
import requests
