After installing python-3.1.2.msi I'm not able to run to python.exe at all because it gives me the following error message:

Fatal Python error: Py_Initialize: can't initialize sys standard streams
LookupError: unknown encoding: cp720

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

PS
* I'm using WinXp SP3 32Bit

[mbnoimi]

I uninstalled python-2.6.3 before installing python-3.1.2.msi

This is a duplicate of bpo-1616979.

[mbnoimi]

No No, this isn't duplicated issue because if I copied cp720.py to Python31\Lib\encodings

Python still crashed and gives me the following error

----
Fatal Python error: Py_Initialize: can't initialize sys standard streams
TypeError: 'NoneType' object is not callable

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

This is the file I'm adding for removing warning message which is not the reason of crashing

humm I re-read bpo-1616979

I'm confused is it really duplicate issue? if yes I couldn't find the way for fixing in bpo-1616979

PS
I'm newbie in Python and I faced this problem in first day I use Python so please forgive me if my discussion is stupid.

For fixing this issue I tried to following:

1. Installed python-2.6.3.msi
2. Downloaded cp720.py, genwincodec.py from http://svn.python.org/view?rev=74000&view=rev
3. Copied cp720.py it to Python31\Lib\encodings
4. Run Python31\python.exe I got the following error:
   ---

Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
  File "C:\Python31\lib\encodings\__init__.py", line 98, in search_function
    level=0)
  File "C:\Python31\lib\encodings\cp720.py", line 50
    u'\x00'     #  0x00 -> CONTROL CHARACTER

5) copied genwincodec.py to Python26
6) Run C:\Python26>python.exe genwincodec.py 720 1>C:\Python31\Lib\encodings\cp720.py I got the following error message:
---

Traceback (most recent call last):
  File "genwincodec.py", line 8, in <module>
    from gencodec import codegen
ImportError: No module named gencodec

What's wrong? that's really exhausted! I didn't face this problem with any programming language before (I'm C++/Qt developer)

Thanks and I'm very sorry for disturbance I'll try to get help through mailing list you've mentioned

[mbnoimi]

Lie Ryan gave me the solution,

copy http://svn.python.org/view/python/branches/py3k/Lib/encodings/cp720.py?view=markup to Python31\Lib\encodings
