Python: Short, Self Contained, Correct Example

Please test your python install environment with this basic example. If this doesn't work, the script won't work.

# module dependencies
import psutil, signal
from selenium import webdriver
import fake_useragent as fake_ua

ua = fake_ua.UserAgent()
proxy_addr = '127.0.0.1:8180'

chrome_options.add_argument('headless')
# https://stackoverflow.com/questions/49565042/way-to-change-google-chrome-user-agent-in-selenium
chrome_options.add_argument(f"user-agent={ua.random}")
chrome_options.add_argument("window-size=1296,1018")
# Disable image downloads; see https://stackoverflow.com/questions/18657976/disable-images-in-selenium-google-chromedriver
chrome_options.add_argument('blink-settings=imagesEnabled=false')
chrome_options.add_argument('mute-audio')
if False:
    # apparently headless Chrome doesn't set preferences
    chrome_options.add_experimental_option("prefs", {"acceptInsecureCerts": True})
# chrome_options.add_argument("--proxy-server={}".format(proxy_addr))
# chrome_options.binary_location=chrome_executable
