Not sure why you would need open anything... Simply readings docs is enough to know how to make requests https://2.python-requests.org/en/master/

result = req.get("https://raw.githubusercontent.com/python-visualization/folium/master/examples/data/world-countries.json")
data = result.json()
print(data)
