a question

[Xinyue Ye]

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?

Can you cut and past the relevant lines from your interactive session?

sys.ps2 is defined in an interactive session only as precised in the doc
