方法一：
用内置函数set:
1 list1 = [1, 2, 3, 3, 4, 4, 5, 6, 6, 6, 7, 8, 9] 2 list2 = list(set(list1)) 3 print(list2)
方法二：
遍历去除重复
1 list1 = [1, 2, 3, 3, 4, 4, 5, 6, 6, 6, 7, 8, 9] 2 list2=[] 3 for i in list1: 4 if not i in list2: 5 list2.append(i) 6 print(list2)
列表推导式
1 list1 = [1, 2, 3, 3, 4, 4, 5, 6, 6, 6, 7, 8, 9] 2 list2=[] 3 [list2.append(i) for i in list1 if not i in list2]
