Python Selenium. Parallelize iteration from excel

Please help.

I am trying to iterate through an excel file made up of 3 columns (IP, Username, Password). The script should read the excel fill line by line.

For line 1 from example, it will open a browser and go to the website with IP address in rows one and when the browser is fully loaded, enter the username and password then submit. Then go to the next line, open a browser, enter the IP and the enter the username and password and submit and then to the next line and so on...

screenshot of the excel I'm working with:

I am about to write a code the does the above sequentially (one after another). But i have challenges writing a code that can do that in parallel for example open 4 browsers at once and run the first 4 lines of the excel and when it is done, open the next 4 browsers for the next 4 lines.

Here is my code below. Please help!!
