I have a C file that has a bunch of #defines for bits that I\'d like to reference from python. There\'s enough of them that I\'d rather not copy them into my python code, i

I had almost exactly this same problem so wrote a Python script to parse the C file. It's intended to be renamed to match your c file (but with .py instead of .h) and imported as a Python module.

Code: https://gist.github.com/camlee/3bf869a5bf39ac5954fdaabbe6a3f437

Example:

configuration.h

#define VERBOSE 3
#define DEBUG 1
#ifdef DEBUG
    #define DEBUG_FILE "debug.log"
#else
    #define NOT_DEBUGGING 1
#endif

Using from Python:

>>> import configuration
>>> print("The verbosity level is %s" % configuration.VERBOSE)
The verbosity level is 3
>>> configuration.DEBUG_FILE
'"debug.log"'
>>> configuration.NOT_DEBUGGING is None
True
