How do you make an array of structs in C?
...
@JohnSmith You are mistaken; read it again. sizeof *students is the size of what's pointed at, i.e. sizeof(STUDENT), not sizeof(STUDENT*). You are making the exact mistake that the ptr = malloc(num * sizeof *ptr) idiom is supposed to guard against. Check...
Unable to import a module that is definitely installed
...g and ImportError, but sudo pip install colorama was telling me "package already installed".
My fix: run pip without sudo: pip install colorama. Then pip agreed it needed to be installed, installed it, and my script ran.

...
@Mackie well if you actually bothered to read the PEP, it explicitly says: The C API remains unchanged; C code will still need to be aware of the difference between short and long ints. (The Python 3.0 C API will probably be completely incompatible.) The PyArg_Pars...
