如何删除矩阵中的重复值？

mat = [[5,6,8] , [8,5,3] , [9,10,3]]
res= []
for i in mat:
    if i not in res:
        res.append(i)
        print(res)
        fit= set(res)
        print(fit)

Answer 1

mat = [[5,6,8] , [8,5,3] , [9,10,3]]
res=[]
for i in mat:
    res+=i
duplicated= set([i for i in res if res.count(i)>1])
new=[]
for i in mat:
    new_in=[]
    for j,val in enumerate(i):
        if val not in duplicated:
            new_in.append(val)
    new.append(new_in)
print(new)

如果你期望你的输出像 [[6], [], [9, 10]]
