如果Python与C一样快，后者会出现在Python应用程序/库中吗？
如果Python和C一样快，那么PIL是否会全部用Python编写？
获取“合法”的C图书馆和OS设施。
当然，您可以使用ctypes来访问现有的C代码，但在足够复杂的情况下，您可能不必要：当您编写的代码面向C设计的接口（并在其内部实现）时，不进行编译可能意味着呼叫方的小错误在C中无法正确编译，可能会导致整个应用程序崩溃。
因此，为了重用优秀的现有C代码，使用C代码（而不是ctypes）是有意义的（当然，Cython也可以，因为它生成的C代码，在调用者端出错时应该无法编译;-)。
不管怎样,从零敲碎打中提取一切东西,而不是利用好、现有的、坚固的和经过细微调整的代码,都没有什么意义——当然还有这么多令人感兴趣的新问题需要加以消化,而用你的时间只是把现有的、公正的解决方法推向一个<>old<>strong>和已经引起争论的问题,很可能<>not<>em> > > /em>将是你花时间的最佳、最有成效、最令人满意的方式;
使用C模块在Python中是有意义的，因为：
关于你的例子：是的，但是 Python 本质上比 C 慢。如果它们两个速度相同，使用 Python 是有意义的，因为 C 代码往往更容易受到攻击（缓冲区溢出等）。
