How to pass variable to escaped js string?

Question

Python

I'm trying to display an alert with the value of my variable in selenium, but I don't quite understand how to pass it to an escaped string, I will be grateful for any help

value = "bar"
driver.execute_script('''
foo = value;
alert(foo);
''')

Answer 1

value = 'bar'
driver.execute_script("foo = \'" + value + "\'; alert(foo);");

Answer 2

You can use f-strings (a relatively new thing).

f'''
foo = {value};
alert(foo);
'''

If you need support for older versions of python, then use string formatting

'''
foo = {value};
alert(foo);
'''.format(value=value)
