There's more than one way to do it! (Oh, sorry, that's Perl...)

The two most standard ways would be to call strip() on your string to get
one sans both leading and trialing whitespace

    print h.strip()

or if you know exactly what you've got (i.e., the newline you don't want is
just the last character), you can just get rid of it:

    h = h[:-1]
