if not in t). The second one is O(len(t)) (for every element in t remove it from s). So care must be taken as to which is preferred, depending on which one is the longest set and whether a new set is needed.
可以调用add方法为set插入元素: # Add one more item to the set filled_set = some_set filled_set.add(5) # filled_set is now # Sets do not have duplicate elements filled_set.add(5) # it remains as before set还可以被认为是集合,所以它还支持一些集合交叉并补的操作。 # Do set intersection...
Okay, so why did changing the order affect the length of the generated set object? The answer is the lack of intransitive equality only. Since sets are "unordered" collections of unique elements, the order in which elements are inserted shouldn't matter. But in this case, it does matter....
10.delete an item by value with remove() 11.Get an Item by Oset and Delete It with pop() You can get an item from a list and delete it from the list at the same time by using pop(). If you call pop() with an offset, it will return the item at that offset; with no ...

Once we've gone through all the rule lines, we use the set function to consolidate all the duplicates in our list into a single list of unique elements. Finally, our return function gives that information back to the calling code. But not all functions have to have a return value. Now ...
