numba库使用jit(just-in-time)加速python低效的for语句,前面我们提到过C比python快的一个原因是C会先编译好再运行,而jit的原理就是先编译python,让代码变得静态,从而使运行速度更快。 import numba as nb @nb.jit def add_nb(lst): res = [0] * len(lst) for i, ele in enumerate(lst): res[i] =...

, etc. In pure mode, you are more or less restricted to code that can be expressed (or at least emulated) in Python, plus static type declarations. Anything beyond that can only be done in .pyx files with extended language syntax, because it depends on features of the Cython compiler....
