In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...
defaultdict(lambda: "pending"): 使用 lambda 定义了一个简单的工厂函数,返回固定字符串。 嵌套defaultdict: 通过递归定义default_factory,可以轻松创建任意深度的嵌套字典结构,而无需手动检查和创建中间层级的字典。defaultdict_to_dict函数展示了如何将其转换回普通的嵌套字典,这在需要序列化(如 JSON)或进行不依赖defa...
