请问列表删除元素的问题该怎么做？

Question

我想把road里重复的部分删掉，比如['00:03', '00:06'], ['00:06', '00:03']就是一组重复的，请问该怎么办？

road = [['00:03', '00:06'], ['00:06', '00:03'], ['00:0b', '00:07'], ['00:01', '00:02'], ['00:02', '00:08'], ['00:08', '00:02'], ['00:05', '00:07'], ['00:02', '00:03'], ['00:09', '00:0a']]

Answer 1

road = [['00:03', '00:06'], ['00:06', '00:03'], ['00:0b', '00:07'], ['00:01', '00:02'], ['00:02', '00:08'], ['00:08', '00:02'], ['00:05', '00:07'], ['00:02', '00:03'], ['00:09', '00:0a']]
print(road)
'''
先对列表中的字符串排序
'''
for i in range(len(road)):
    road[i].sort()
print(road)

'''
再对road去重，因为是二位列表，需要转换再处理
'''
newroad = list(set([tuple(t) for t in road]))
newroad = [list(v) for v in newroad]

'''
先讲内部元素转化为tuple，然后再使用set，先递归将整个list转化为tuple，tuple是不可变对象
'''
print(newroad)
