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...

To interact with the search service, you'll need to create an instance of the appropriate client class:SearchClientfor searching indexed documents,SearchIndexClientfor managing indexes, orSearchIndexerClientfor crawling data sources and loading search documents into an index. To instantiate a client obj...
While not a purely functional language, Python supports many functional programming concepts, including treating functions as first-class objects. This means that functions can be passed around and used as arguments, just like any other object like str, int, float, list, and so on. Consider the...
The client can instantiate the enumeration so it can be used. Misspelled references to elements of the enum will raise a AttrError exception as: resourceCategory = client.factory.create('resourceCategory') client.service.getResourceByCategory(resourceCategory.PLATFORM) Factory The factory is used to...
