The**kwargsallows to pass keyworded variable length arguments to a method. The**kwargsis used in order to handle named arguments in a function. Example In this example, the functionwelcome_namesdemonstrates how to use**kwargsto handle an arbitrary number of keyword arguments and print them ...

双刃剑. Python’s string literal concatenation feature can work to your benefit, or introduce hard-to-catch bugs. 另外, 最好在容器最后的元素加上逗号 names= ['Alice','Bob','Dilbert', ] 3. Context manager. 上下文管理器 有基于Class(实现__enter__, __exit__)或者contextlib这个库和生成器 ...
