How to Handle (Java-)Script Variables in Python?

Question

This opens a new tab in Firefox browser:

from selenium import webdriver
browser = webdriver.Firefox()
browser.execute_script('''window.open("https://www.google.com/","_blank");''')

As a reference, here is the Selenium documentation:

**execute_script**(script, *args)
Synchronously Executes JavaScript in the current window/frame.
Args:
script: The JavaScript to execute.
*args: Any applicable arguments for your >JavaScript.
Usage:
driver.execute_script(‘return document.title;’)

I have a link in a String which I wish to open in a new tab using javascript (via execute_script).

Tried the following but it gives an error:

link = 'https://www.bing.com/'
java_script = '\'\'\'window.open(\"' + link + '\",\"_blank\");\'\'\''
browser.execute_script(script)

Error:

selenium.common.exceptions.JavascriptException: Message: SyntaxError: unexpected token: string literal

• Ahmed I. Elsayed: use r"string" or """string""" and just don't escape anything
• Ahmed I. Elsayed: and to handle variables, execute say "let x = 2; return 2;" and capture this in a python variable, it will work
• Yacine Mahdid: Check out f string, there are well suited for the case where you want to put a variable in the middle of a string

Answer 1

F-string are well suited for that check them out

This will change your code to look like this:

from selenium import webdriver
browser = webdriver.Firefox()
link = 'https://www.bing.com/'
browser.execute_script(f"window.open('{link}','_blank');")

• AcerWolf: If you add single quotation marks around the curly brackets like (f"window.open('{link}','_blank');") it works as wished. Thanks for helping!
• Yacine Mahdid: Cool! I'll add it to the answer
