six should be mentioned as dependency of sage in build/deps.

comment:3 follow-up: Changed 5 years ago by jdemeyer

Isn't there a Python-3 equivalent of 

sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0)

Changing the print statement is not equivalent to changing stdout.

Replying to jdemeyer:

sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0)

Changing the print statement is not equivalent to changing stdout.

I agree, but no there isn't a python 3 equivalent: python 3 requires sys.stdout to be buffered, unless you start python with the -u (but you can also do that with python 2).

Not sure, but isn't there something possible with sys.stdout.buffer in Python 3?

Replying to jdemeyer:

It allows you to write bytes to stdout: sys.stdout.buffer is a BytesIO interface to stdout, whereas sys.stdout is a StringIO interface to stdout.

Assuming that you actually tested this, positive_review since the diff looks good.

Apparently you haven't actually (doc-)tested it ;-)
