Index.The index() function in Python searches lists. We pass it a value, and it returns the index where that value is found. If no value is found, it throws an error. With count,we count the matching elements in a list. Like index() this loops through and tests each element in a...
heap queue是“queue algorithm”算法的python实现,调用_heapq.nlargest()返回了根据每个value排序前n个大的(key, value)元组组成的列表。具体heap queue使用参见文档。 elements elements方法实现了按照value的数值重复返回key。它的实现很精妙,只有一行: def elements(self): '''Iterator over elements repeating each ...
