No, and you'll know why if you check for the number of university and
college computer science students  learning Python in their
introductory programming course (not the number of  institutions  that
teach a little bit in a physics course), and the number of textbooks
available to support that (and not free online or print tutorials).
There's just not a big enough market for (traditional) publishers to
be interested in publishing them or (traditional) authors in writing

Preiss ( translated his original
C++  text (1999)  into a number of other languages: Java (2000), C#
(2001),  Python (2003), and Ruby (2004). So he could easily afford to
Translate the early money-makers into less used languages because the
initial writing overhead was no longer an issue--and much of the
tyranslation was "automated". And he uses his free online versions to
help market the publishe'rs small (relative to C++ and Java) print
runs, so they can afford to service this very small market.

DSA--formerly (i.e., in the "Good Old Days") just Data Structures-- is
or was,  in the "usual" CS curriculum (a la ACM+IEEE)  at least, a
second-level course based on CS1; hence, "most efficiently" taught
using the students' introductory language (if it's at all suitable,
and texts are available) so only some finer points of the language
needed covering and one can concentrate on implementation of the data
structures themselves. 

So very  little CS1 in Python translates into very little--and
probably even less--CS2, etc., in Python.
