This Python package allows you to fetch the current user-agent strings for popular browsers. It uses web scraping to fetch the user-agent strings from the website useragentstring.com.
The package contains two main scripts:
-
get_user_agent_pls_scraper.py: This script scrapes the user-agent strings for various browsers from useragentstring.com and saves them in a JSON file (user-agents.json). The browsers it fetches the user-agent strings for are Edge, Chrome, Firefox, Safari, and GoogleBot. -
get_user_agent_pls.py: This script fetches a user-agent string. If theUSER_AGENT_API_KEYenvironment variable is not set, it uses the locally saveduser-agents.jsonfile. If the file doesn't exist, it callsget_user_agent_pls_scraper.pyto fetch and save the latest user agents. If theUSER_AGENT_API_KEYenvironment variable is set, it uses the API to fetch the user-agent string.
- Install the package using
pip install get_user_agent_pls. - Import the
fetch_user_agentfunction from theget_user_agent_plsmodule. - Call the function with the browser and operating system as arguments. The available options for the browser are "Edge", "Chrome", "Firefox", "Safari", and "GoogleBot". The operating system argument is currently not used. For example,
fetch_user_agent("chrome", "windows").
