While try to run Python.exe version 3.1 or 3.2 RC2 on
Windows 7 or Windows XP SP2 get the following error:

Py_Initialize: Can't initialize system standard streams
Lookup Error: unknown encoding: cp720

after download and install cp720.py to lib/encodings get the following error:

Py_Initialize: Can't initialize system standard streams
TypeError: 'NoneType' object is not callable

this is while IDLE works fine

two questions:

• where did you obtain cp720.py, are you sure it was a python3 version?
• I've never seen a "3.2 RC2" version. Did you mean the py3k branch?

[Hamedji]

in fact i'm not sure it is compatible with python 3.1
i have download it from

http://blog.oneortheother.info/tip/python-fix-cp720-encoding/

[amauryfa]

cp720.py was added a few months ago, and will be available with 3.2.
for the impatient, it's here:
