What does the use_subprocess argument do in this line of code?
driver = uc.Chrome(use_subprocess=True, options=chrome_options)
I have looked for a while but i cant find anything

This is what I wrote below. I am using PyCharm 2022.2.2 (Community Edition)
Build #PC-222.4167.33, built on September 15, 2022
from selenium import webdriver
# Chrome driver = Path
#to open an URL in a BROWSER
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
name = "Trainer"
service_obj = Service(r"C:\Users\DS-02\Desktop\Manjit\chromedriver.exe") #---- doesn't works
driver = webdriver.Chrome(Service = service_obj)
The error which I am getting is below:
C:\Users\DS-02\AppData\Local\Programs\Python\Python310\python.exe C:\Users\DS-02\Desktop\Manjit\PythonSelenium\Class_1_demo_Browser.py
Traceback (most recent call last):

driver = webdriver.Chrome(Service = service_obj) #----- doesn't works
TypeError: WebDriver.__init__() got an unexpected keyword argument 'Service'
Please help,
Thanks and regards
I have tried the code below and works sometime now it doesn't works. I want to fix the code above:
#driver = webdriver.Chrome(executable_path = service_obj)
#driver = webdriver.Chrome(executable_path = '../Webdriver/chromedriver.exe')
Please help
You need to change this line driver = webdriver.Chrome(Service = service_obj) to be
driver = webdriver.Chrome(service = service_obj)
Parameter to be passed into webdriver.Chrome() in order to initialize driver object should be lowercased service while Service in your code is this:
selenium.webdriver.chrome.service, you called it Service here:
from selenium.webdriver.chrome.service import Service
This error message...
TypeError: WebDriver.__init__() got an unexpected keyword argument 'Service'
...implies that when the program execution starts the int() method counters an unexpected keyword argument 'Service'.
Details
With the availability of selenium4 the key executable_path() is deprecated and you have to use the key service.
However you need to take care of couple of things as follows:
Incase you use the service keyword you have to create a Service object and assign the absolute location of the ChromeDriver, you have to import:
from selenium.webdriver.chrome.service import Service
The keyword within webdriver.Chrome() is service. So you have to:
service_obj = Service('C:\\Users\DS-02\\Desktop\\Manjit\\chromedriver.exe')
driver = webdriver.Chrome(service = service_obj)
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver=webdriver.chrome(executable_path="C:\Driver\chromedriver_win32\chromedriver.exe")
driver.get("www.youtube.com")
print (driver.title)
driver.close()
for the above code I'm getting the error
TypeError: 'module' object is not callable
I recommend modular programming.
Set a function that returns the chrome driver like such:
# Opens chrome driver
def openChrome():
# directory to chromedrive
chromeDriver = "C:\Driver\chromedriver_win32\chromedriver.exe"
return webdriver.Chrome(chromeDriver)
Call this function like this:
url = "https://stackoverflow.com/"
driver = openChrome()
driver.get(url)
So in the future if your driver isn't working, you don't have to change it on every script you will change it in one place (function)
options = FirefoxOptions()
options.add_argument("--headless")
driver = webdriver.Firefox(firefox_options=options, executable_path='/Users/toprak/Desktop/geckodriver')
driver.get("https://twitter.com/login?lang=en")
When I try to run my code, I get this error:
Warning (from warnings module):
File "/Users/toprak/Desktop/topla.py", line 19
driver = webdriver.Firefox(firefox_options=options, executable_path='/Users/toprak/Desktop/geckodriver')
DeprecationWarning: use options instead of firefox_options
Traceback (most recent call last):
File "/Users/toprak/Desktop/topla.py", line 19, in <module>
driver = webdriver.Firefox(firefox_options=options, executable_path='/Users/toprak/Desktop/geckodriver')
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/firefox/webdriver.py", line 137, in __init__
if options.binary is not None:
AttributeError: 'Options' object has no attribute 'binary'
When I delete the lines which are about options and take out "firefox_options=options", the code works fine. What should I do to fix this?
Instead of using firefox_options object you need to use options object. Additionally you need to use the headless attribute. So your effective code block will be:
options = FirefoxOptions()
options.headless = True
driver = webdriver.Firefox(executable_path='/Users/toprak/Desktop/geckodriver', options=options)
driver.get("https://twitter.com/login?lang=en")

You can find a couple of relevant detailed discussions in:
How to make Firefox headless programmatically in Selenium with Python?
The --headless argument works fine in Firefox (geckodriver) these days.
If you're getting the error mentioned in the title, then you're probably accidentally creating or passing a Chrome-based Options object rather than a Firefox-based Options object.
To avoid that mistake, it's best to create an import alias for both of them so that they're easier to distinguish.
from selenium.webdriver.chrome.options import Options as ChromeOptions
from selenium.webdriver.firefox.options import Options as FirefoxOptions
chrome_options = ChromeOptions()
chrome_options.add_argument('--headless')
chrome_driver = webdriver.Chrome(executable_path = r"..\mypath\chromedriver.exe", options=chrome_options)
firefox_options = FirefoxOptions()
firefox_options.add_argument('--headless')
firefox_driver = webdriver.Firefox(executable_path = r"..\mypath\geckodriver.exe", options=firefox_options)
Executing below code in pycharm.
from selenium import webdriver
browser = webdriver.Firefox
browser.get('https://www.google.com')
Error:
TypeError: get() missing 1 required positional argument: 'url'
How can I solve the error?
Specify the path the chrome driver is located in for example when calling
webdriver.Firefox(‘C://Users/Username/Downloads/‘)
This worked for me:
from selenium import webdriver
driver = webdriver.Chrome("C:\\Users\Rishabh\Downloads\chromedriver_win32\chromedriver.exe")
driver.get('https://web.whatsapp.com/')
Alternate code:
from selenium import webdriver
driver = webdriver.Chrome(executable_path="C:\\Users\Rishabh\Downloads\chromedriver_win32\chromedriver.exe")
driver.get('https://web.whatsapp.com/')
In my case, I got this error for not using parenthesis ().
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('https://www.google.com')
Try with braces while creating Firefox instance. see below example.
from selenium import webdriver
browser = webdriver.Firefox() #focus on () at the end
browser.get('https://www.google.com')
The constructor is driver = webdriver.Firefox(). So in your code block you need to replace driver = webdriver.Firefox with:
driver = webdriver.Firefox()
Additionally, you may need to pass the absolute path of the GeckoDriver binary as follows:
driver = webdriver.Firefox(executable_path=r'C:\path\to\geckodriver.exe')
The issue is caused bacause there are not,()pharentesis, put the pharantesis end to the line
Check this
In Selenium and python
driver = webdriver.Chrome()
i have problem when running this code :
>>> from selenium import webdriver
>>> driver = webdriver.firefox()
Traceback (most recent call last):
File "<pyshell#19>", line 1, in <module>
driver = webdriver.firefox()
TypeError: 'module' object is not callable
i have searched for the problem and i got some results. but unfortunately , they didn't work. So , how can i solve this?
thanks.
You have made a typo.
webdriver.Firefox()
Note the capital F.
the same goes for other browsers!
e.g.
webdriver.chrome Vs. webdriver.Chrome
(its even harder to notice this!)
thanks so much for the help! ;)
Another way is:
from selenium.webdriver import Chrome.
driver = Chrome()
When typing "Chrome" Note the capital C.
You probably gonna need to specify the executable_path for chromedriver.exe:
driver = Chrome(executable_path="path_in_here")
This error message...
TypeError: 'module' object is not callable
......implies that your program is trying to call a python module.
You need a minor modification in the offending line of code. You have used:
driver = webdriver.firefox()
Where as firefox is a module for example as in:
selenium.webdriver.firefox.options
So you have to change firefox() to Firefox() and your effective line of code will be:
driver = webdriver.Firefox()
Likewise:
For Chrome:
driver = webdriver.Chrome()
For Internet Explorer:
driver = webdriver.Ie()
