print(name) # 输出:Bob, Charlie(排除Alice) 适用场景: 需要基于多个字典或集合的键进行复杂过滤。 总结与推荐 方法 核心逻辑 适用场景 注意事项 直接遍历/.keys() 默认或显式获取键 简单遍历 优先使用,代码简洁 sorted() + 遍历 按键排序后遍历 需要有序遍历 需注意性能(大字典可能较慢) 字典推导式 遍历时...
6. 字典的遍历 items方法可返回一个键值对列表，通过for循环逐一处理。 keys方法返回所有键的列表。 values方法返回所有值的列表。 可以结合sorted函数对键或值进行排序。 如果需要去除值的重复，可以将值转化为集合。7. 字典的嵌套 字典可以嵌套使用，如字典列表、列表作为字典值，甚至是字典作为字典值。

So, to order the tuples (1, 2, 4) and (1, 2, 3) lexicographically, you would switch their order to (1, 2, 3) and (1, 2, 4). Because of Python’s lexicographic sorting behavior for tuples, using the .items() method with the sorted() function will always sort by keys unless...
