calling c functions from python

I have some code written in c that i want to call from python. Is there a way to do this. I looked at several documentations but they look quite vague. Can some one give me some specific steps please

Edit:

I wrote below dll called djj.dll
it has a file called try.cpp with following code

#include

int print(){


return 4;

}

Now, i build this dll and go to python idle.

I type print windll.djj.print . It gives syntax error .WHY??
