尽管存在参数 y，但为什么会出现错误“TypeError: set_window_position() missing 1 required positional argument: 'y'”？

Question

Anyone has an idea why the error appears despite the argument is present? :) This is my code:

from selenium import webdriver
import time
import datetime
from selenium.webdriver.chrome.webdriver import WebDriver

opt = webdriver.ChromeOptions()
# opt.add_argument("--start-maximized")

listOfLinks = open("test.txt", "r")
#  open test page in the browser
browser: WebDriver = webdriver.Chrome('C:\\Users\\Valeriia\\PycharmProjects\\selen\\chromedriver.exe', options=opt)
page = browser.get('https://stackoverflow.com/questions/ask')
time.sleep(5)
browser.set_window_position({'x': -4, 'y': -1})
browser.set_window_size({'width': 1448, 'height': 1085})

Answer 1

You provide a dict as a single parameter however the function requires 2 (x and y).

Try instead:

browser.set_window_position(**{'x': -4, 'y': -1})

or:

browser.set_window_position(x=-4, y=-1)

or:

browser.set_window_position(-4, -1)

Answer 2

You're providing the arguments to browser.set_window_position in a dictionary, but it is expecting the result in a different format. Both of these should work:

browser.set_window_position(x=-4, y=-1)

or

browser.set_window_position(-4, -1)

Alternatively, if you store the dictionary somewhere else and pass it in, you can use the double-asterisk syntax to unpack it as a set of keyword arguments:

coordinates = {'x':-4, 'y':-1}
browser.set_window_position(**coordinates)
