大家好，欢迎来到 Crossin 的编程教室。 作为每天都在用 Python 工作的开发者，我最常听到大家的吐槽就是：“Python 写起来是真爽，但跑起来也是真慢！” 尤其是在处理一些大量计算或者跑数据的时候，看着控制台半天不跳下一个进度条，恨不得进去推它一把。

Numba 是 python 的即时（Just-in-time）编译器，即当你调用 python 函数时，你的全部或部分代码就会被转换为“即时”执行的机器码，它将以你的本地机器码速度运行！它由 Anaconda 公司赞助，并得到了许多其他组织的支持。 在 Numba 的帮助下，你可以加速所有计算负载 ...

But in many cases, it doesn’t have to be an either/or proposition. Properly optimized, Python applications can run with surprising speed—perhaps not as fast as Java or C, but fast enough for web ...

Optimized apps and websites start with well-built code. The truth, however, is that you don't need to worry about performance in 90% of your code, and probably 100% for many scripts. It doesn't matter ...

PyPy is a drop-in replacement for the stock Python interpreter, and it runs many times faster on some Python programs. Python has earned a reputation for being powerful, flexible, and easy to work ...

The C API of CPython is one of the cause of the success of Python in scientific computing. In particular, Numpy (and all the Python scientific stack) is built on top of this API. However, some ...

INTERVIEW Python creator Guido van Rossum last week introduced a project to make CPython, the official implementation, five times faster in four years. Now Mark Shannon – one of the three initial ...
