Option 2

If you’re super keen on using backslashes, you could do something like this:

backslash_char = "\"
my_string = f"{backslash_char}foo{bar}"

But that’s probably not the best way to make your code readable to other people.

If you’re absolutely certain you’ll never use a particular character, you could also put in that character as a placeholder, something like

my_string = f"🍔foo{bar}".replace("🍔", "\\")

But that’s also super workaround-y. And it’s a great way to introduce bugs down the road, if you ever get an input with that char in it.
