builtins.TypeError: doit être str, pas d'octets

J'ai converti mes scripts de Python 2.7 à 3.2 et j'ai un bogue.

# -*- coding: utf-8 -*-
import time
from datetime import date
from lxml import etree
from collections import OrderedDict

# Create the root element
page = etree.Element('results')

# Make a new document tree
doc = etree.ElementTree(page)

# Add the subelements
pageElement = etree.SubElement(page, 'Country',Tim = 'Now', 
                                      name='Germany', AnotherParameter = 'Bye',
                                      Code='DE',
                                      Storage='Basic')
pageElement = etree.SubElement(page, 'City', 
                                      name='Germany',
                                      Code='PZ',
                                      Storage='Basic',AnotherParameter = 'Hello')
# For multiple multiple attributes, use as shown above

# Save to XML file
outFile = open('output.xml', 'w')
doc.write(outFile)

Sur la dernière ligne, j'ai eu cette erreur:

builtins.TypeError: must be str, not bytes
File "C:\PythonExamples\XmlReportGeneratorExample.py", line 29, in <module>
  doc.write(outFile)
File "c:\Python32\Lib\site-packages\lxml\etree.pyd", line 1853, in lxml.etree._ElementTree.write (src/lxml/lxml.etree.c:44355)

J'ai installé Python 3.2, et j'ai installé lxml-2.3.win32-py3.2.exe.

Sur Python 2.7, cela fonctionne.

Le fichier de sortie doit être en mode binaire.

outFile = open('output.xml', 'wb')

Convertir un fichier binaire en base64 et vice versa. Prouver dans python 3.5.2

import base64

read_file = open('/tmp/newgalax.png', 'rb')
data = read_file.read()

b64 = base64.b64encode(data)

print (b64)

# Save file
decode_b64 = base64.b64decode(b64)
out_file = open('/tmp/out_newgalax.png', 'wb')
out_file.write(decode_b64)

# Test in python 3.5.2
