[issue31467] cElementTree behaves differently compared to ElementTree

[Ravikumar]

New submission from Ravikumar:

I have started learning python and I see below snippet fails. I do not 
understand how to fix the issue and assume this might be a bug in 
multiprocessing library.

I use Python 2.7.12


My python snippet

import xml.etree.ElementTree as ET# WORKS
import xml.etree.cElementTree as ET# DOES NOT WORK
import multiprocessing

tree = ET.parse('country_data.xml')
root = tree.getroot()

manager = multiprocessing.Manager()
elems_saved = manager.dict()

elems_saved["1"]=root


/tmp/Python$ cat country_data.xml

141100




/tmp/Python$


OUTPUT

/tmp/Python$ python testxml.py 
Traceback (most recent call last):
  File "testxml.py", line 10, in 
elems_saved["1"]=root
  File "", line 2, in __setitem__
  File "/usr/lib/python2.7/multiprocessing/managers.py", line 758, in 
_callmethod
conn.send((self._id, methodname, args, kwds))
TypeError: expected string or Unicode object, NoneType found

Please let me know if I am wrong

Ravikumar added the comment:

Just now I have figured out that , in the documentation it was mentioned that 
cElementTree module is deprecated in Python 3.3 version. 

"The xml.etree.ElementTree module implements a simple and efficient API for 
parsing and creating XML data.

Changed in version 3.3: This module will use a fast implementation whenever 
available. The xml.etree.cElementTree module is deprecated."

https://docs.python.org/3/library/xml.etree.elementtree.html


In that case, will your resolution comment still holds valid ??
If so then, how to use cElementTree in my usecase
