Textbooks on Perl/Python

[Jalab]

Greetings all,
Any help in finding a university level textbook on the subject of
"Scripting languages" I am mainly looking for a book that covers Perl
and Python only as the 2 main scripting languages and that is written
for students, i.e. chapter summary, exercises, etc. I hate to force my
student to buy and study from two separate books.

Any ideas?
Thanks.
