Python carriage return vs newline

What’s the difference between \n [newline] and \r [carriage return]?

In particular, are there any practical differences between \n and \r? Are there places where one should be used instead of the other?

I would like to make a short experiment with the respective escape sequences of \n for newline and \r for carriage return to illustrate where the distinct difference between them is.

I know, that this question was asked as language-independent. Nonetheless, We need a language at least in order to fulfill the experiment. In my case, I`ve chosen C++, but the experiment shall generally be applicable in any programming language.

The program simply just iterates to print a sentence into the console, done by a for-loop iteration.

Newline program:

#include 

int main[void]
{
    for[int i = 0; i < 7; i++]
    {
       std::cout
