1 """ 2 找出列表中两数之和为特殊值,比如8的组合 3 """ 4 number_lists = [] 5 numbers = [2, 3, 5, 8, 7, 4, 1, 6] 6 for number in numbers: 7 for number1 in numbers: 8 if number+number1 == 8: 9 number_tuple = number,number1 10 number_tuple1 = number1,number 11 if number_tuple and number_tuple1 not in number_lists: 12 number_lists.append(number_tuple) 13 print(number_lists)
改进
1 for number in numbers: 2 for number1 in numbers: 3 if number+number1 == 8 and (number,number1) not in number_lists and (number1,number) not in number_lists : 4 number_lists.append((number,number1)) 5 print(number_lists)
这里的列表的append元组,用法很新颖
number_lists.append((number,number1))
