C++ Vs Python?

[MrD.]

Python has also been around longer so I believe it's more known.

Hmm, time-line of programming languages.
C: 1972
C++: 1983
Python: 1991

Also, the standard Python implementation, CPython, is written using C, so no, Python hasn't been around longer than C/C++.

C++ is faster than python but python is cross-platform lang.

The C++ language is cross-platform, the core language and libraries just don't offer high-level abstractions for as much stuff as Python (which is why cross platform C++ can be more difficult since there is a large combination of compiler/operating system quirks to take into consideration).

I will agree though, that Python has been implemented on pretty much everything nowadays (since all you really need is a C compiler to build CPython).
