在Python中,我们在遍历列表的时候,可以通过enumerate方法来获取遍历时的index,比如: >>> items = 'zero one two three'.split() >>> print list(enumerate(items)) [(0, 'zero'), (1, 'one'), (2, 'two'), (3, 'three')] >>> for (index, item) in enumerate(items): print index, item ...
看看这个:>>> leaf2 = LeafUA() >>> leaf2.ping() <instance of LeafUA>.ping() in LeafUA <instance of LeafUA>.ping() in U <instance of LeafUA>.ping() in A <instance of LeafUA>.ping() in Root >>> LeafUA.__mro__ # doctest:+NORMALIZE_WHITESPACE (<class 'diamond2.LeafUA'>...
我们甚至可以将这些步骤分为两个连续的组：“标记前步骤”（用于修改句子结构的步骤）和“标记后步骤”（仅用于修改单个标记的步骤），以避免重复标记步骤。 但是，为简单起见，我们使用.split（）函数。将推文解析为字符串列表之后，就可以开始创建函数了。 顺便说一句，我在列表周围使用了一个名为tqdm的漂亮模块，...

delim_whitespace :boolean, default False. #指定空格(例如’ ‘或者’ ‘)是否作为分隔符使用,等效于设定sep='\s+'。如果这个参数设定为Ture那么delimiter 参数失效。 1. 2. 3. 4. 5. 6. 7. 8. 常用参数(对于数据读取有表头和没表头的情况很实用) ...
