I'd like to know if it is possible to use ctypes to access C++ DLLs from Python and run functions (or class methods) from them.If not, is there another way to do this?

New in Python version 2.5 is the ctypes, a foreign function library. It provides C-compatible data types and allows calling functions in DLLs or shared libraries.
The only field is _fields_ , which is a list of tuples. Each tuple is (<variable-name>, <ctypes. TYPE>) . ctypes has types like c_char ( char ), and c_char_p ( *char ). ctypes also includes POINTER() which creates a pointer type from any type passed to it.
This question has been answered many times (this one is an exact duplicate!)
In summary, no you can't do it with Ctypes (yet) but there are a number of other code generators you could use to do the job. SWIG and Boost.Python are two of the most popular.

the boost python library makes it REALLY easy to wrap a C++ class and expose it as python module. It took me around 10 minutes the first time I tried.
