首先,我们需要创建一个空字典。在 Python 中,你可以使用花括号{}来创建一个空字典。 AI检测代码解析 my_dict={} 1. 步骤2: 添加键值对 接下来,我们需要向字典中添加一些键值对。键(key)是唯一的,而值(value)可以是任何数据类型。 AI检测代码解析 my_dict['apple']='fruit'my_dict['carrot']='vegetable...

python以其优美的语法和方便的内置数据结构,赢得了不少程序员的亲睐。 其中有个很有用的数据结构,就是字典(dict),使用非常简单。说到遍历一个dict结构,我想大多数人都会想到 for key in dictobj 的方法,确实这个方法在大多数情况下都是适用的。但是并不是完全安全,请看下面这个例子: ...
