How does this string concatenation work?

I have some text and I want concatenate them, but they're too long. So I can do this:

b = 'Hello\n'\
    'Hi\n'\
    'This is a test'

print(b)

Output:

Hello
Hi
This is a test

But today I find a new way to do this, and this way is more clearer. Like this:

a = ('Hello\n'
     'Hi\n'
     'This is a test')

print(a)

Output:

Hello
Hi
This is a test

So now my question is: How does it work? Why does it wouldn't create a tuple or raise a SyntaxError?

http://stackoverflow.com/questions/10660435/pythonic-way-to-create-a-long-multi-line-string there are numerous ways to create a multipline string, this is one of them – Padraic Cunningham Sep 20 '15 at 13:29
@PadraicCunningham Thanks :). – Remi Guan Sep 20 '15 at 13:31
Because `'a' 'b'` is a valid expression, and is equivalent to `'ab'` – Huazuo Gao Sep 20 '15 at 13:45
@HuazuoGao And if strings in brackets can wrap without backslash? :) – Remi Guan Sep 20 '15 at 13:52
@KevinGuan line breaks inside a bracket are ignored. – Huazuo Gao Sep 20 '15 at 14:16
@HuazuoGao I understand now, thanks :) – Remi Guan Sep 20 '15 at 14:16
