Many of the concepts you've learned will carry over. Though, you'll still need to learn syntax and the little idiosyncrasies between the languages. If/else, while loops, input/output etc are common to many (if not most/all, I'm only familiar with a few so can't say for sure:P) languages, though there are certainly some differences in the specifics of how they work. It will be things such as pointers and references, polymorphism, garbage collection, and such that sound like they'll be new concepts to you. They're "basics" of C++ but you'll still likely be learning things like loops and in/out for some time before getting into them. Maybe take a look at what the concepts are for pointers and references, but I wouldn't recommend trying to jump ahead without learning the "basics-basics". But, everything you've learned will certainly be helpful in picking up a new language.

The basics of C++ are similar to Python, and again, I don't think you'll hit any entirely new concepts until pointers and references, though perhaps I'm overlooking something. There will be little specifics that are new, such as in C++ variables not being in scope outside of a loop they're created in or the way functions handle arguments, but I don't imagine it will be anything you can't wrap your head around. Going from a high language like Python to C++ will take a little getting used to but should be manageable.

My Python is super rusty and I haven't practiced with it as much as I ought to lately though, so perhaps someone else will have different or better advice though :)

Good luck!

A few things that will pop up when jumping into C++ from a scripting language...

1: If you want to use strings ( or don't want to write overly complex code to handle strings ) , better memorize this line of code

using namespace std; // some folks don't like using it due to "conflicts"

2: "<<" = output ... ">>" = input

// << is also the equivalent of + 
cout << "Hello World !" << endl;
// or
cout << "Hello " << "World !" << endl;

3: Variable types have to be declared !

4: Don't attempt pointers until you understand memory management "do s" and "don't s"

5: Learn how to write header files correctly

6: C++ classes do not quite work the same as Python's classes . C++ classes can be dangerous to new comers due to manual memory management requirements.
