Hmm, that's odd, it works for me. Can you check what the following
expressions insert:

(let ((pyfile (make-temp-file "test" nil ".py")))
  (unwind-protect
      (progn (let ((inhibit-eol-conversion nil))
               (with-temp-file pyfile
                 (insert "print('hello world')\n")))
             (call-process "python2" pyfile '(t t) nil
                           "-i" "-u"))
    (delete-file pyfile)))

(let ((pyfile (make-temp-file "test" nil ".py")))
  (unwind-protect
      (progn (let ((inhibit-eol-conversion t))
               (with-temp-file pyfile
                 (insert "print('hello world')\n")))
             (call-process "python2" pyfile '(t t) nil
                           "-i" "-u"))
    (delete-file pyfile)))

I get this for the first (where ^M is really a carriage return character)

    Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40)
      [MSC v.1500 64 bit (AMD64)] on win32
    Type "help", "copyright", "credits" or "license" for more information.
    >>>   File "<stdin>", line 1
        print('hello world')^M
                            ^
    SyntaxError: invalid syntax
    >>>

and this for the second:

    Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40)

    >>> hello world
