我正在尝试将python bool转换为C ++ bool,以便它可以用于比较,但无法成功获取它。
这是我到目前为止的代码(注释掉以前的试验以供参考)。任何帮助将不胜感激。到目前为止,它应该打印“True”和“False”,但我无法在C ++ if语句中正确评估它。

编辑:
py::object mwparser = py::module::import("mwparserfromhell");
py::object code = mwparser.attr("parse")(py::str(text));
py::object filtered = code.attr("filter_templates")();
for(auto temp : filtered) {
//auto type = template_figure_type(temp.attr("name"));
auto type = template_figure_type(py::str(temp.attr("name")));
// py::print("G ");
//py::print(type);
// auto type = "";
if(type != ""){
try {
//list.append(type);
//return list;
//py::print(py::str(type));
py::object f = temp.attr("has")("link");
py::print(py::str(f)); //displays "True" and "False" when it should
//PyObject *t = Py_True;
// int tr = PyObject_IsTrue(f);
// if(py::str(f) == py::str("False")) {
if(py::str(f).is(py::str("True"))) {
//if(temp.attr("has")("link")) {
//if(py::str(f) == py::str("True")){
// if(0){
temp.attr("remove")("link");
bContent_changed = true;
list.append(temp);
}
else {
py::print("NO");
}
} catch (std::domain_error) {
throw std::domain_error("");
}
}
似乎有效,但已被弃用。当我尝试使用建议的“f.is(Py_True)”时,它会产生错误if(f == Py_True){

看来这可以通过以下对上面代码段的更改来解决
f.is(Py_True)
应该是
if(py::str(f).is(py::str(Py_True)))
希望这有助于其他可能有同样问题的人。重要的是要注意,虽然已弃用,但&#39; ==&#39;比较(f == Py_True)仍然有效(暂时)。
对于那些好奇的(正常运行的)更新代码如下:
py::object mwparser = py::module::import("mwparserfromhell");
py::object code = mwparser.attr("parse")(py::str(text));
py::object filtered = code.attr("filter_templates")();
for(auto temp : filtered) {
auto type = template_figure_type(py::str(temp.attr("name")));
if(type != ""){
try {
py::object f = temp.attr("has")("link");
py::print(py::str(f)); //displays "True" and "False" when it should
if(py::str(f).is(py::str(Py_True))){
temp.attr("remove")("link");
bContent_changed = true;
list.append(temp);
}
else {
py::print("NO");
}
} catch (std::domain_error) {
throw std::domain_error("");
}
}

检查此功能
int PyBool_Check(PyObject * o) 如果o的类型为PyBool_Type,则返回true。
