Is this valid Python 3? 

print

comment:4 Changed 6 years ago by jdemeyer

  • Status changed from needs_info to needs_work

Well, it's technically valid but it doesn't do what you think it does: 

Python 3.3.2 (default, Dec  7 2013, 12:59:33) 
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print
<built-in function print>

comment:5 Changed 6 years ago by jdemeyer

One more detail, since you're changing the code anyway. Change this 

        if b.obj_constant_term > self._backend.zero(): print("+ {}".format(b.obj_constant_term))
        elif b.obj_constant_term < self._backend.zero(): print("- {}".format(-b.obj_constant_term))

to 

        if b.obj_constant_term > self._backend.zero():
            print("+ {}".format(b.obj_constant_term))
        elif b.obj_constant_term < self._backend.zero():
            print("- {}".format(-b.obj_constant_term))

which is much more readable

comment:6 Changed 6 years ago by jdemeyer

Same for 

        if d > self._backend.zero(): print("+ {} ".format(d))
        elif d < self._backend.zero(): print("- {} ".format(-d))

comment:11 Changed 6 years ago by mkoeppe

You missed several backends

comment:12 Changed 6 years ago by chapoton

The aim is to have the doctests pass when adding a global future print import in sage/all.py.

For that, all the backends where something was needed were modified.

You can check this by adding from __future__ import print_function in src/sage/all.py on top of this branch and running all the tests in the numerical folder.

If you want to take the opportunity to convert everything else to python3 print style in the numerical folder, please do.

Yes, as I said, you missed some backends. I've done the remaining ones.

comment:16 follow-up: Changed 6 years ago by chapoton

ok, I had forgotten about the optional backends, indeed.

Why did you change two print to sys.stdout.write ?

comment:17 in reply to: ↑ 16 Changed 6 years ago by mkoeppe

Replying to chapoton:

Why did you change two print to sys.stdout.write ?

These are print-without-newlines.

comment:18 Changed 6 years ago by chapoton

ok, then I am happy with your commit. Are you ok with mines ?

comment:19 Changed 6 years ago by mkoeppe
