How to Load WebDriver for Different Browsers Dynamically in Python?

You can write a Python program with Selenium Client Python API to Load WebDriver for Different Browsers Dynamically This can be done by specifying the WebDriver server program path name when initializing the WebDriver client object.

1. Make sure you have browser drivers installed locally in a single folder:

C:\fyicenter> dir \fyicenter\selenium

         8,393,728 chromedriver.exe
        14,478,647 geckodriver.exe
           149,176 MicrosoftWebDriver.exe

2. Enter the following program, WebDriverLoader.py, that offers a function to load WebDriver by browser name:

C:\fyicenter> type WebDriverLoader.py

# WebDriverLoader.py
# Copyright (c) FYIcenter.com 
from selenium.webdriver import Chrome
from selenium.webdriver import Edge
from selenium.webdriver import Firefox
import sys

def load(name):
   if (name=="Chrome"):
      driver = Chrome("\\fyicenter\\selenium\\chromedriver.exe")
   elif (name=="Edge"):
      driver = Edge("\\fyicenter\\selenium\\MicrosoftWebDriver.exe")
   else:
      print("ERROR: Invalid browser name: "+name)
   return driver

driver = load(sys.argv[1])
driver.get("http://www.google.com")
driver.quit()

3. Test with Chrome and Edge browsers:

C:\fyicenter> python WebDriverLoader.py Chrome

C:\fyicenter> python WebDriverLoader.py Edge

You will see both browsers loaded correctly.
