python – How to let Selenium use the DEFAULT webdriver in operating system?

I would set driver in this function to any web-driver the user may using, through it’s quite hard, Because lots of different web-drivers are be used.

Here’s code:

from selenium import webdriver

def login() -> dict:
    driver = webdriver.ChromiumEdge()
    driver.get("https://an.url")
    cookies = None
    while cookies == None:
        cookies = driver.get_cookie("COOKIES")
        if cookies != None:
            cookies = {cookies["name"]: cookies["value"]}
            driver.close()
            break
    return cookies

I found that when I used driver = selenium.webdriver.Safari() (There’s NO Safari in Windows), it raised selenium.common.exceptions.NoSuchDriverException. I tried to write all web-driver into a list then check if they could raise this exception. However it not happend. It just got stuck. Error log of NoSuchDriverException below.

>>> from selenium import webdriver
>>> driver = webdriver.Safari()

The above exception was the direct cause of the following exception:
