eg: 特殊操作: 1.链式赋值 2.交叉赋值 3.解压赋值 3 1 2 [3, 1, 2] # _是合法的变量名,会接受值,但我们认为_代表该解压位不用接收,用_来接收表示
That means that the program reads each text file three times. You can use the walrus operator to avoid the repetition:Python wc.py import pathlib import sys for filename in sys.argv[1:]: path = pathlib.Path(filename) counts = ( (text := path.read_text()).count("\n"), # ...

赋值表达式(Assignment Expressions)又称为"海象操作符"(the Walrus Operator)或"命名表达式"(Named Expressions), 是python3.8依赖提供的新功能。这功能褒贬不一,用的好的话事半功倍,用不好的话会成为代码坏味道的催化剂。本期视频通过实例演示,让大家认识赋值表达式的
Python's walrus operator := allows you to assign a value to a variable within an expression, combining assignment and use in a single step.
