上述代码中,我们首先定义了一个函数check_duplicate_elements,该函数接受一个列表作为输入。在函数内部,使用set数据结构将列表转换为集合,并通过比较集合和列表的长度来判断是否存在重复元素。如果长度不相等,则表示列表中存在多个相同元素,函数返回True;否则,返回False。最后,我们定义了一个示例输入列表example_list,并调用...

empty_list = []动态数组性质 列表在Python中扮演着动态数组的角色。这意味着它的容量并非固定不变，而是可以根据需要自动调整。当你向列表中添加更多元素时，它会悄无声息地扩大“口袋”；反之，若移除元素，它又能适时地收缩，避免浪费宝贵的内存空间。这种特性使得列表成为处理大量不确定数量数据的理想选择。可变性...
You can also use the set() function to convert other iterable objects such as lists, tuples, strings, and range objects into sets. If there are duplicate elements in the original data, only one will be kept when converting to a set; if the original There are unavailable values in the ...
