Thanks for the trick! I know now how new I am to the Windows.

Below is the installation message, and the unittest message.

Suspecting there are differences between Linux and Windows on '\n', I
 install pyPDF2 on Ubuntu. It has the same error. What the hell of pyPDF2
 is? I don't know what use/purpose of its test script for. This process is
 also for my learning on Python. Does anyone have the same or different 
 experiences on pyPDF2?

Thanks again.
