Print Functions

Question

The code:

print(*range(1, int(input())+1), sep='')

The problem:
I know what the code does, but can anyone explain to why it does what is does, piece by piece? I know what "print(int(input))" means. As always, thank you in advance!

Answer 1

If you don't mind a few follow ups:

*range() removed the brackets. How?

I'm assuming sep=" has something to do with how the ints are separated. Is this correct?

Thanks again for the assist!
