"Essential Reference", and I would say that Python is definitely a
bigger, and more complicated language than C++. In some aspects it has
simpler syntax. But consider all of the ways that you can pass
arguments to a function, for instance. There are definitely alot more
options than in C/C++. I like the way that both of these languages
In C++, you can pass:
I used the word *arguments*, not parameters. FWIW, *const* seems to
correspond to immutable, pretty well. I find Python to be more more
like Java, with regard to "passing objects by reference".
- by value (with a const or non-const parameter)
(where the value can be a pointer or a non-pointer
or a pointer-to-member or a unique_ptr or a shared_ptr)
- by reference
- by const reference
- by rvalue reference
- by universal reference
- by name (in macros)
- you can overload functions with the same name
but different numbers of parameter or different
types for their parameters
- you can write templates for functions with ranges of types
for a parameter
- default values can be declared for parameters
In Python, you pass
- by value
The section 6.3.4 on calls "in The Python Language
Reference, Release 3.6.0" encompasses 1½ pages.
You are sounding like a "know-it-all" again. I am familiar with such
examples. One could code in C++ for a long time without a definitive
need for templates.
Ok, so if we exclude from C++ everything that you have not
learned yet, than, what is left over, is "much easier" for
you to read "at a glance". It seems that you want C++ to be
adjusted to your knowledge of it and your assertions about
it. I think that one should instead adjust one's assertions
to the reality.
The Python Language Reference, Release 3.6.0 146 pages
latest ISO-C++ draft (without the library part) 464 pages
Bear in mind that you don't have to know every feature of a language to
make good use of it, unless, perhaps, that is your job. I don't believe
reading the latest "ISO-C++ draft" would be a good use of my time; it
sounds like a document geared more to compiler designers. I don't even
try to memorize <cmath>. If I need a function, I search for it.
There is a reason that C++, Java and Python all coexist. It might be
helpful for you to try to appreciate that.

Bill
