Interacting with C and Python
Stephen E. P. Smith · Apress eBooks · 2019
In the early days of microcomputers, like the Apple II, people wrote complete applications in Assembly language, such as the first spreadsheet program VisiCalc. Many video games were written in Assembly to squeeze every bit of performance they could out of the hardware. These days, modern compilers like the GNU C compiler generate fairly good code and microprocessors are much faster; as a result, most applications are written in a collection of programming languages, where each excels at a specific function. If you are writing a video game today, chances are you would write most in C, C++, or even C#, then use Assembly for performance, or to access parts of the video hardware not exposed through the graphics library you are using.
