Question

Good Day Ahead. After searching numerious posts in Stackoverflow, I tried to write and implement the automation using selenium and python programming. I tried my first code as below and i am getting error. My browser opens and closes very fast. It throws error in the output.

Code:-

import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

s=Service(ChromeDriverManager().install())
chrome_driver = webdriver.Chrome(service=s)

browser = webdriver.Chrome("/home/halovivek/Documents/Automation/selenium_driver/")
browser.implicitly_wait(5)
browser.get("https://www.google.com")
#browser.get("https://kite.zerodha.com/")
browser.implicitly_wait(5)

Error:-

I don't understand why this line comes

browser = webdriver.Chrome("/home/halovivek/Documents/Automation/selenium_driver/")

After you already properly created webdriver instance with

s=Service(ChromeDriverManager().install())
chrome_driver = webdriver.Chrome(service=s)

?
Looks like your code should be as following:

import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

s=Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)

driver.implicitly_wait(5)
driver.get("https://www.google.com")

UPD
To make your browser stay opened add "detach", True option, as following:

import time
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_experimental_option("detach", True)

s=Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s, chrome_options=chrome_options)

driver.implicitly_wait(5)
driver.get("https://www.google.com")
