What does execute_script() in Selenium does

Question

browser.execute_script("window.open('about:blank', 'tab2');")
browser.switch_to.window("tab2")
browser.get('http://bing.com')

I was searching online ways to open a new tab using selenium in python, and the method of ctrl + t wasn't working on chrome so I stumbled on the above piece of code, however I am not able to understand what 'excute_script' does.

Answer 1

execute_script method allows to execute JavaScript passed as string argument

Note that you can pass data from Python code into JavaScript code using arguments, e.g.

hello = "Hello"
friends = " friends"

browser.execute_script('alert(arguments[0], arguments[1]);', (hello,  friends))
