• Python 3.10: 炫酷特性值得尝试
  • REAL PYTHON

Explore some of the coolest and most useful features in Python 3.10. You’ll appreciate more user-friendly error messages, learn about how you can handle complicated data structures with structural pattern matching, and explore new enhancements to Python’s type system.

(是也乎:

改进了 error message, 加强了模式匹配, 拓展了 pattern, 比如:

def greet(name):
    match name:
        case "Guido":
            print("Hi, Guido!")
        case _:
            print("Howdy, stranger!")

嗯哼, Elixir 们的语法;

def fizzbuzz(number):
    mod_3 = number % 3
    mod_5 = number % 5

    match (mod_3, mod_5):
        case (0, 0):
            return "fizzbuzz"
        case (0, _):
            return "fizz"
        case (_, 0):
            return "buzz"
        case _:
            return str(number)

• 是什么定义了 Python 中的数字? 问题可能出乎我们的意料...
  • STACK OVERFLOW
  • • Shared by Alex Waygood

Static type-checkers such as Mypy have grown increasingly popular in recent years in the Python community, yet it’s surprisingly difficult to write a type hint that will accept any number. This answer on Stack Overflow digs into why.

• 为毛总是感觉大家都在玩代码 Glof ?
  • REDDIT

Why explicit is better than implicit, or in Martin Fowler’s words: “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.”

Have you wanted to create a Python application that goes further than a command-line interface? You would like it to have a friendly interface but don’t want to make a GUI (Graphical User Interface) or web application. Maybe a TUI (Text User Interface)would be a perfect fit for the project. This week on the show, it’s Will McGugan talking about his projects Textual and Rich.
