List<Person> newList = new ArrayList<>(list.size()); list.forEach(i -> { if (!newList.contains(i)) { newList.add(i); } }); newList.forEach(p -> System.out.println(p)); // 去重方式2:获取循环的值,如果存在两个相同的值,移除相同的值 System.out.println(" *** 自定义去重操作...

Python Code: # Define a function 'checkSubset' that checks if all elements of 'input_list2' are contained in 'input_list1'defcheckSubset(input_list1,input_list2):returnall(map(input_list1.__contains__,input_list2))# Create two lists 'list1' and 'list2'list1=[[1,3],[5,7],[9...
If the sets contain the same elements, regardless of their order, the comparison will return “Equal”. Otherwise, it will return “Not equal”.if set(my_list1) == set(my_list2): print("Equal") else: print("Not equal") # Equal...
python 写一个 check list python check_output,功能说明:使用python编写一个计算器,实现简单的加减乘除功能。程序的逻辑很简单,取出括号,计算里面的乘除加减,结果替换原括号内容,再循环直到最终结果。难点在于正则匹配字符和计算细节上,怎么很好协调配合并正确获得
