Actually, you could also have said:

str2 = "here" "we" "are"

and gotten the concatination. Python automatically
concatinates string literals that come together. That
makes it a bit easier to split a literal across lines.
Admittedly, it's not the most obvious behavior,
although I believe it's faster since it happens in the
lexer (or the parser, but anyway at compile time).
