<p>Yes. While the modified textbooks might share some similarities with SICP, Python and Scheme are extremely different “styles” of programming and are also used for completely different things.
Python is used heavily in the industry and has highly popular applications in scientific computing, software testing, and web application development, for example.</p>
<p>Scheme is a fairly interesting language and makes you think about things in a different way than the C/C++/Java/Python family of languages. That makes it a language worth learning eventually, but not a language you would necessarily want to master initially.</p>
