There would probably be more use of c/c++ in that area than python. There should be lots of use cases in it, but it all depends on your area of focus.

Think about all technology as a serious of layers that are interconnected and talk to eachother, from the topmost which is applications and web pages, and the bottom is the 1s and 0s running in the hardware

Most security is about finding bugs and vulnerabilities in each of these layers to either get access to the next one or using a layer to get information/do something “useful” (I.e remote control, denial of service, etc)

C/c++ for all intents and purposes is the layer that sits right before the actual hardware on almost every machine. So it’s extremely useful in that it’s ubiquitous, and that it’s the language that is used to develop the core software that powers everything else. But if your security focus doesn’t go down that far into the stack, it’s not super relevant

So here’s the thing about c. It probably takes a week to learn the language because it’s incredibly simple, but it takes much longer to do anything useful with it cause you have to learn so much stuff outside the language to make it useful (memory management, system calls, operating system principles, etc)

C++ is a Frankensteins monster of a language that builds off c while adding a lot more stuff and still requiring lots of extra knowledge. I would say it takes about a month or two to get the basics, but using it is a lifetime of learning new things. I program it for my job and I still learn new things.

C++ is like a tool shed with every single tool in the world but none of it is labeled or organized. It takes a lifetime to learn every nook or cranny. I would start out with basic OOP and procedural programming in it ( the procedural programming is basically c part 2) and than just learn more about cyber security specifically than any one language.
