pyscript文件夹下建立一个头文件， 命名为
py_docs.h:

PyDoc_STRVAR(createCellEntity_docs,
"sha3_512([data]) -> SHA3 object\n\
\n\
Return a new SHA3 hash object with a hashbit length of 64 bytes.");

PyDoc_STRVAR(createCellEntityInNewSpace_docs,
"sha3_512([data]) -> SHA3 object\n\
\n\
Return a new SHA3 hash object with a hashbit length of 64 bytes.");

然后将所有api的英文描述写入，PyDoc_STRVAR。
未来如果有其他文档资源， 当前可以通过api文档生成这个py_docs.h

ENTITY_METHOD_DECLARE_BEGIN(Baseapp, Entity)
SCRIPT_METHOD_DECLARE("createCellEntity", createCellEntity, METH_VARARGS, 0， createCellEntity_docs)
SCRIPT_METHOD_DECLARE("createCellEntityInNewSpace", createCellEntityInNewSpace, METH_VARARGS, 0, createCellEntityInNewSpace_docs)
