Question

def name_hui(i,j,k): '''由4个数字组成3位数的回文数字 ''' for i in range(1,5): for j in range(1,5): for k in range(1,5): if i == k or i != j: if i==k or i == j: print(i,j,k) name_hui(0,0,0)

Answer 1

def palindrome_four(nums: list) -> list:
    """由4个数字组成3位数的回文数字 """
    result = []
    for i in nums:
        for j in nums:
            for k in nums:
                if i == k:
                    s = str(i) + str(j) + str(k)
                    if s in result:
                        continue
                    result.append(s)
    return result


print(palindrome_four([1, 1, 3, 4]))
