The following written assuming you are as new to programming generally
as to python specifically.
If not then please excuse me. it is written based on this line:

It is completely natural that you assume learning programming means
learning a programming language.
And in that context python is as good a choice as you could make.

However the assumption is wrong-headed.

Sure you cannot program without using some programming language. Yet
knowing a programming language does not do much by way of knowing
programming.
Look up any of the online resources on computer science and you will
find courses/material on a variety of stuff such as:
- operating systems
- compilers
- data structures
- algorithms
- a variety of almost unrelated flavors of math (eg graph theory,
discrete math, numerical analysis)
- a variety of almost unrelated flavors of theory (eg semantics,
automata theory etc)
- then all sorts of 'modern' stuff eg web/security/cloud etc

Somewhere in all this you would find a course on programming languages
and an intro course on programming -- probably using python or some
other language.

Now I will admit that this 'classical' approach is often misguided and
has wrong emphasis.
I have a series of blog posts starting
http://blog.languager.org/2011/02/cs-education-is-fat-and-weak-1.html
on the mess in CS education.

However the mess in CS education notwithstanding, the fact does not
change that for a 'sound educational background' you should be
spending 1/5 your time on a specific programming technology such as
python and the remaining on more generic stuff such as Ive listed above
