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

Question

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

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:

Answer 1

Check below:

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

Answer 2

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).

Comments

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"
