What is the best way of using C++ standard std::string from cython? The last cython distribution should make it easy anyway, but I wonder why there are wrappers for std::vector and not for std::string...

The std::string class manages the underlying storage for you, storing your strings in a contiguous manner. You can get access to this underlying buffer using the c_str() member function, which will return a pointer to null-terminated char array. This allows std::string to interoperate with C-string APIs.
Overview. Cython has native support for most of the C++ language. Specifically: C++ objects can be dynamically allocated with new and del keywords.
Cython improves the use of C-based third-party number-crunching libraries like NumPy. Because Cython code compiles to C, it can interact with those libraries directly, and take Python's bottlenecks out of the loop.
std::string class in C++ C++ has in its definition a way to represent a sequence of characters as an object of the class. This class is called std:: string. String class stores the characters as a sequence of bytes with the functionality of allowing access to the single-byte character.
Cython 0.16 includes wrappers for std::string, which can be imported with:
from libcpp.string cimport string
