Compare and swap instruction in python

Question

Is it possible to have a CAS instruction in python? CAS = compare and swap.

I'm looking for something equivalent for expression in C++:

std::atomic<T> a;
a.compare_exchange_strong(x, y);

Answer 1

Python doesn't have CAS operation. As you know CAS is an atomic instruction used in multithreading to achieve synchronization. C++ has a much more sophisticated multithreading and synchronization than Python.
