Cython,Python,C/C++的运行速度对比

关于Cython,Python,C/C++的运行速度的对比
测试环境：
处理器： AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx 2.10 GHz
机带： RAM 8.00 GB
系统：Windows 10 21H2 （19044.1499）
(Cython 编译的指令为：python setup.py build_ext --inplace
测试结果如下

下面给出测试的代码
C++：

#include#include#include#include#pragma comment(lib,"winmm.lib")int a, b, c, d;void detect(void*);int main(){long long int sum = 0;a = 0, b = 0, c = 0, d = 0;_beginthread(detect, NULL, NULL);DWORD t1, t2;t1 = timeGetTime();for (a = 0; a < 1000; a++){for (b = 0; b < 1000; b++){for (c = 0; c < 1000; c++){for (d = 0; d < 1000; d++){sum = a + b + c + d;}}}}t2 = timeGetTime();std::cout << "time used:" << t2 - t1 << std::endl;system("pause");}void detect(void*){while (1){if (a == 1000 && b == 1000 && c == 1000 && d == 1000){_endthread();}else{std::cout << "a=" << a << "b=" << b << "c=" << c << "d=" << d << "n";system("cls");}}}

下面给出Python的代码

import timeimport osa=0b=0c=0d=0def main(): e=0 t1=time.time() for a in range(0,1000): for b in range(0,1000): for c in range(0,1000): for d in range(0,1000): e=a+b+c+d os.system('cls') print('a=', a, 'b=', b, 'c=', c, 'd=', d) t2=time.time() print("time used:",t2-t1)if __name__=='__main__': main()

Cython给出的代码太复杂了，这里就不写出来了
