Answer 1

Yes you can use qrcode:

import qrcode
import qrcode.image.svg

img = qrcode.make('http://www.google.com/', image_factory=qrcode.image.svg.SvgImage)

with open('qr.svg', 'wb') as qr:
    img.save(qr)

will this open. a. url if the user scans the code? – Serotherapy

This depends on the QR code reader software the user uses to scan the QR code, some readers automatically open the URL some just display it and the user needs to do an additional click. Don't forget that the QR code just encodes information and doesn't store any action associated to/with it. – Ignition

Answer 2

You can use google apis to create qr code without additional library:

import requests

WIDTH = 400
HEIGHT = 400

DATA = "http://www.google.com/"

image = requests.get(f"https://chart.googleapis.com/chart?chs={WIDTH}x{HEIGHT}&cht=qr&chl={DATA}")
image.raise_for_status()

with open("qr.png", "wb") as qr:
    qr.write(image.content)
