在这个判断重复值的情况下,设计一个简单的类来封装逻辑也是一个好主意。 ListChecker+list my_list+set unique_values+check_duplicates() : void+add_value(value) : void 这个类ListChecker负责检查一个列表中的重复值,实现一个check_duplicates方法来执行这一检查,并定义一个add_value方法用于添加值到集合中。
This means we only scan the main list once. We do scan the unique items list for each entry in the main list, but even in a worst case this greatly reduces the number of comparisons. Fastest implementation: Use a Set lookup Those two examples let us check for duplicates. The improved ...
在Python中,列表(List)是一种有序的、可重复的数据结构。我们可以通过比较列表的长度和去重之后的列表的长度来判断是否存在重复元素。代码示例如下: AI检测代码解析 defcheck_duplicates(data):iflen(data)==len(list(set(data))):returnFalseelse:returnTruedata=[1,2,3,4,5,5]result=check_duplicates(data)p...
