Big magic in python 2.7.15 win version:

Create file: "xml.py" containing 2 code lines:

import xmlrpclib

proxy = xmlrpclib.ServerProxy("http://localhost:8000/")

run it, and it gives u a nice error:
C:\work\mitre>\Python27\python.exe xml.py
Traceback (most recent call last):
  File "xml.py", line 1, in <module>
    import xmlrpclib
  File "C:\Python27\lib\xmlrpclib.py", line 538, in <module>
    from xml.parsers import expat
  File "C:\work\mitre\xml.py", line 3, in <module>
    proxy = xmlrpclib.ServerProxy("http://localhost:8000/")
AttributeError: 'module' object has no attribute 'ServerProxy'


U also get this error, when this file present in the directory where u want to import xmlrpclib in another py. ANd if only the compiled xml.pyc exist, the bug comes.  But if you rename it to xm.py, it works!

Maybe a bad import from wrong directory in xmlrpclib. Not tested on another version or platform.
