当数据不应该被复制时,例如因为数据太大或者函数设计需要在原地更改数据以使调用者受益时,调用list()会很糟糕。在这种情况下,像isinstance(x, abc.MutableSequence)这样的运行时检查将是一个好方法。如果你担心得到一个无限生成器——这不是一个常见问题——你可以先调用len()来检查参数。这将拒绝迭代器,同时安全...
dictionary = {'item1':10,'item2':20}print(dictionary['item2']) 这将输出20。我们不能使用相同的键创建多个值。这将覆盖重复键的先前值。字典上的操作是唯一的。字典不支持切片。 我们可以使用 update 方法将两个不同的字典合并为一个。此外,如果存在冲突,update 方法将合并现有元素: ...
