I've converted my scripts from Python 2.7 to 3.2, and I have a bug.
# -*- 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)
On the last line, I got this error:
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)
File "c:\Python32\Lib\site-packages\lxml\etree.pyd", line 478, in lxml.etree._tofilelike (src/lxml/lxml.etree.c:90649)

I've installed Python 3.2, and I've installed lxml-2.3.win32-py3.2.exe.
On Python 2.7 it works.
The outfile should be in binary mode.
outFile = open('output.xml', 'wb')
Convert binary file to base64 & vice versa. Prove in 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
