Python: Using an existing google chrome profile with selenium chrome web driver

0 votes

I want to load my existing google chrome profile with all chrome extensions.

It is throwing some error. Below is the code also:

chrome_options = Options()

chrome_options.add_argument('user-data-dir= C:\Users\DMMaxim\AppData\Local\Google\Chrome\User Data')

capabilities = DesiredCapabilities.CHROME.copy()

chromedriver = r"C:\Users\DMMaxim\Desktop\chromedriver_win32\chromedriver.exe" 

driver = webdriver.Chrome(executable_path=chromedriver, chrome_options = chrome_options, desired_capabilities=capabilities)

Below is the error:

C:\Users\DMMaxim\Desktop>python ExportbacktestTradingview.py

  File "ExportbacktestTradingview.py", line 21

    chrome_options.add_argument('--user-data-dir=C:\Users\DMMaxim\AppData\Local\Google\Chrome\User Data')

                               ^

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 18-19: truncated \UXXXXXXXX escape

Below is my source code:

from selenium import webdriver

from selenium.webdriver import ActionChains

from selenium.webdriver.chrome.options import Options

from selenium.webdriver.common.keys import Keys

from selenium.webdriver.common.by import By

from selenium.webdriver.support.ui import WebDriverWait

from subprocess import Popen

from time import gmtime, strftime

from os import system

import sys

timer=0

chrome_options = Options()

chrome_options.add_argument('user-data-dir= C:\Users\DMMaxim\AppData\Local\Google\Chrome\User Data')

capabilities = DesiredCapabilities.CHROME.copy()

chromedriver = r"C:\Users\DMMaxim\Desktop\chromedriver_win32\chromedriver.exe" 

driver = webdriver.Chrome(executable_path=chromedriver, chrome_options = chrome_options, desired_capabilities=capabilities)

driver.get("https://www.tradingview.com/chart/gK6Rq0UH/")

driver.implicitly_wait(90)

driver.find_element_by_xpath("""//*[@id="footer-chart-panel"]/div[2]/span[4]""").click()

driver.implicitly_wait(90)

while True:

    driver.implicitly_wait(90)

    driver.find_element_by_xpath("""//*[@id="bottom-area"]/div[2]/div[1]/div[2]/ul/li[4]""").click()

    driver.implicitly_wait(90)

    timer=timer+1

    time.sleep(1)

    if timer > 250:

The problem is with the string

"C:\Users\Eric\Desktop\beeline.txt"

Here, \U starts an eight-character Unicode escape, such as '\U00014321`. In your code, the escape is followed by the character 's', which is invalid.

You either need to duplicate all backslashes, or prefix the string with r (to produce a raw string).

Hi @Shinio. Can you please explain what you mean by "duplicate all backslashes"

Hi @John, I think what @Shinio meant to say by "duplicate all backslashes" is to add additional backslashes to the path string i.e. if the Path is: 

"C:\Users\Eric\Desktop\beeline.txt" 

then to avoid the escape character error use this: 

"C:\\Users\\Eric\\Desktop\\beeline.txt"
