[Python 2.6] print_function and unicode_literals cannot be used atthe same time?

[ÖܼÃÊÇĸÀÏÊó]

Any ideas?

Code 1:

from __future__ import print_function, unicode_literals
import sys
print(type('HELLO, WORLD!'), file=sys.stderr)

Result 1:

<type 'str'>

Code 2:

from __future__ import unicode_literals, print_function
import sys
print(type('HELLO, WORLD!'), file=sys.stderr)

Result 2:

File "tmp.py", line 3
print(type(''), file=sys.stderr)
^
SyntaxError: invalid syntax

Code 3:

from __future__ import unicode_literals, print_function
import sys
print >> sys.stderr, type('HELLO, WORLD!')

Result 3:

<type 'unicode'>

You have to do each future import in a separate line:

<type 'unicode'>

That's a bug, isn't it? The language reference explicitely allows it:

Yes, and Benjamin Peterson already submitted a patch because of this thread.

It will be fixed in 2.6.1.
