Before I use the Python 2.7.2 on Windows XP, today I tried to upgrade to the Python 2.7.3, but encountered a problem.
When running any .py file encountered "import unicodedata" or directly run the command always returns:
Traceback (most recent call last):
......
 import unicodedata
ImportError: DLL load failed: 找不到指定的程序。
"找不到指定的程序" corresponding English is "Cannot find the specified program".
I unable provide more information because I am only a user rather than developer.
After that, I manually delete "C:\Python27\DLLs\unicodedata.pyd" file (this step must be, otherwise no effect), then reinstall (Repair) Python 2.7.2 the problem disappeared.
