Python Selenium TypeError：__init__() 需要 1 个位置参数，但给出了 2 个

Question

My webscraper doesn't work. It's giving me this error, "TypeError: init () takes 1 positional argument but 2 were given."

I get that error when I tried opening with Edge, Chrome, and Firefox.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Edge(executable_path="C:\\Users\.......\Python\Python37-32\Lib\site-packages\selenium\edgedriver_win64\msedgedriver.exe")
driver.set_page_load_timeout(30)
driver.get("https://www.udemy.com/topic/python/")
driver.quit()

I looked at example code from other people and it looked the same as what I did.

Also, the program is in the D drive while the edgedriver_win64 is in the C drive. I don't know if that makes a difference though.

Here is the full stack trace:

Answer 1

I had several issues with the webdriver module finding my exact location of the driver even if it was in the same folder. This was because if you are running this as a script I believe python by itself checks Its own scripts folder first for any kind of driver executable.

I was able to solve this issue by placing the msedgedriver.exe, chromedriver.exe, etc in my python scripts folder. I hope this helps. Then I was able to run driver = webdriver.Edge()

I am really confused. My code looks the same as all of the examples that I have seen but I am still getting this error, "TypeError: init() takes 1 positional argument but 2 were given."

The full stack trace is posted.
