The batch file is something like this, I put the python in some directory that has SPACE character in its path.

C:\"Documents and Settings"\Administrator\Desktop\bracket\python\python 
C:\\"Documents and Settings"\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py

When I run this one, I get this error.

C:\Documents and Settings\Administrator\Desktop\bracket\python\python: can't ope
n file 'C:\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\bra
ckettest.py': [Errno 2] No such file or directory
C:\Documents and Settings\Administrator\Desktop\bracket>

What might be wrong?

Wrapping the path doesn't solve this problem.

"C:\\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py"

Are the brackets ('[]') cause of the problem? On Mac, python works well with bracket character.
