Selenium Remote Webdriver gives JSONDecodeError

Question

My code is:

import unittest
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.common import desired_capabilities

class test_mycode(unittest.TestCase):
    def setUp(self):
        desired_cap = {'browser': 'IE', 'browser_version': '8.0', 'os': 'Windows', 'os_version': '7', 'resolution': '1366x768'}
        self.driver = webdriver.Remote(command_executor='http://username:[e-mail]:80/wd/hub', desired_capabilities=desired_cap)

    def test_website(self):    
    .....

Mistake:

Traceback (most recent call last):

selenium-server-standalone2.48.0 is installed and running.

Python - 3.5

This is the code I wrote to run Selenium in a browser. I followed the instructions given by the browser, however, when I started it, it raised a JSONDecodeError.

I also changed command_executor to http : //127.0.0.1-00-00444/wd/hub , but that failed. Then I changed the desire_capabilities = wish_cap property to the desired .DesireCapabilities.FIREFOX qualities, but it also crashed.

I googled everywhere but can't find any answer. Can someone help? Thank you very much.

, 2 , , , - . desired_cap json. , https://jsonlint.com/.

- :

desired_cap = {'browser': 'IE', 'browser_version': '8.0', 'os': 'Windows', 'os_version': '7', 'resolution': '1366x768'}
desired_cap = desired_cap.replace('\\'', '\\"')
