It works Ok for me, 
can you cut and paste the full session so we can 
see exactly what is happening. 

Also, what environment are you running it in? 
Windows/Linux/MacOS?
IDLE, Pythonwin, Pycrust?

All of that might be relevant.

when I type sys.ps2 after import sys,
I got the message like:
Traceback (most recent call last):
 File "<pyshell#10>", line 1, in -toplevel-
  sys.ps2
AttributeError: 'module' object has no attribute 'ps2'
why does it happen?
