字典D={"张三":88,"李四":98},向字典D中添加键值对"钱七":90的代码是()
举一反三
- 字典D={"张三":88,"李四":98},向字典D中添加键值对"钱七":90的代码是() A: D["钱七"]=90 B: ["钱七"]=90 C: "钱七":90 D: "钱七"=90
- 下列字典创建的合法语句是: A: dic=("张三":90,"李四":85,"王二":88) B: dic={"张三":90,"李四":85,"王二":88} C: dic=["张三":90,"李四":85,"王二":88] D: dic={"张三",90,"李四",85,"王二",88}
- 下列不能创建字典对象的语句是： A: dic=dict({("张三",90),("李四",85),("王二",88)}) B: dic=dict([("张三",90),("李四",85),("王二",88)]) C: dic=dict((("张三",90),("李四",85),("王二",88))) D: dic=dict(("张三",90,"李四",85,"王二",88))
- 假设字典 student = {"张三":2001, "李四":2001, "王五":2001}，以下哪个选项的作用是为这个字典添加一个 A: student["张三"] = 2002 B: student["Henry"] = 2001 C: student["李四"] += 1 D: del student["李四"]
- 输出字典fruits中键值最大的键值对，完善代码。fruit...format(m,fruits[m]))
