unable to understand the syntax regarding valueError

I am a bit confused about why we need quotations after parenthesis why is it not print("{}").format(err)) instead in the video it shows print("{})".format(err))

except ValueError as err: print("Oh no! Thats not a valid value") print("{})".format(err))

Hello, Just to clarify, you're wondering why the code block is:

except ValueError as err:
    print("Oh no! That's not a valid value. Try again..")
    print("({})".format(err))

And not

except ValueError as err:
    print("Oh no! That's not a valid value. Try again..")
    print("{}".format(err))

If that's the case, I'll recommend you try using the same values using the first code and then trying without those parenthesis. You'll notice that is merely aesthetic in this case. But if you try to delete the quotations, then you'll get an error, because quotations make a STRING and those can be formatted with the .format method.

Just try experimenting and moving this around, and also keep in mind style it makes things easier to read for everyone else
