C++ 11 开始支持 UTF-8、UTF-16 和 UTF-32 字符串常量的声明,分别使用 u8""、u"" 和 U"" 作为声明的标志 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 #include <codecvt> #include <fstream> #include <iostream> intmain() { conststd::locale utf8...

比如,C 语言用「#include」,PHP 语言可以用「include、include_once、require、require」。而 Python 用的是「import」。 Python 可以导入整个模块、模块的一部分或模块中的特定函数。C 语言?你可以查看「/usr/include/」。Python 的话,最好用「python -v」列出所有路径,然后从列表中搜索每个目录和子目录中的每个...
在Cpython 的根目录使用 make regen-grammar命令来运行pgen重新编译 Grammar 文件。应该看到类似于此的输出,表明已生成新的Include/graminit.h和Python/graminit.c文件:下面是部分输出内容 # Regenerate Include/graminit.h and Python/graminit.c # from Grammar/Grammar using pgen PYTHONPATH=. python3 -m Parser...

一般pybind11 都是用于给 C++代码封装 Python 端接口,但是反过来 C++调 Python 也是支持的。只需#include <pybind11/embed.h>头文件即可使用,内部是通过嵌入 CPython 解释器来实现。使用上也非常简单易用,同时有不错的可读性,与直接调用 Python 接口非常类似。比如对一个 numpy 数组调用一些方法,参考示例如下: ...
