generated Constants in Python
I'm using SWIG to create a Python interface to my C++ class library.
I can't work out how to utilise the constants created by SWIG in Python . I can't even print their value.
For example, both these print statements in Python fail silently...
print CONST1
print rep (CONST1)
In C++ , I have this
#define CONST1 0x20000
const int CONST2 = 0x20000; // No different to #define in SWIG-generated code.
If I look at the Python module created by SWIG it has something like this...
CONST1 = _theCPPlibrary.CONST1
Additionally, I tried using the SWIG %constant directive as an experiment (I don't really want to use this if I can avoid it, as it involves duplicating my constants in the SWIG input file). The %constant directive also gives the same results.
I'm a C++ programmer, and a noob in Python.
After build, you will get a python source file: theCPPlibrary.py, and a pyd file: _theCPPlibrary.pyd. You must import the python module first:
import theCPPlibrary
CONST1 is defined by #define, it can be access by:
print theCPPlibrary.CONST1
CONST2 is defined by const, is't a global variable, access it by:
print theCPPlibrary.cvar.CONST2
