Can someone help me under ```Except ValueError as err:```?

I specifically don't understand as err. What is it for? It seems like if you have one exception handling line, then you just leave it there with your print statement. But if you are adding a second one, you have to use the as err, and then you have to format it into your print statement. I don't understand why, whatsoever. I've seen it like 3 times in my lesson but it was never explained why we use it. For example (imagine this makes sense, there was something I did written just like this in a course):

try:
    message = print(int("What's your favorite color?  "))
except TypeError:
    print("Oh no, something went wrong")
except ValueError as err:
    print("This isn't right {}" .format(err))

i tried google but nothing explains it in english.
