Python在IEEE“顶级编程语言”中排名第一 IEEE.ORG “Python dominates as the de facto platform for new technologies” and “Learn Python. That’s the biggest takeaway we can give you from its continued dominance of IEEE Spectrum’s annual interactive rankings of the top programming languages. You don’t have to become a dyed-in-the-wool Pythonista, but learning the language well enough to use one of the vast number of libraries written for it is probably worth your time.” skybison: Instagram 的实验性能面向 Feenfield Python 实现 GITHUB.COM/FACEBOOKEXPERIMENTAL “Skybison is experimental performance-oriented greenfield implementation of Python 3.8. It contains a number of performance optimizations, including: small objects; a moving GC; hidden classes; bytecode inline caching; type-specialized bytecode; an experimental template JIT.” 如何在定义 Python 函数时使用可选参数 REAL PYTHON In this tutorial, you’ll learn about optional arguments in Python and how to define functions with default values.
