无法获取数组中2个相等数字的两位数

def find_two_digit_number(nums):
    count = {}
    result = []

    # 统计数字出现的次数
    for num in nums:
        if num in count:
            count[num] += 1
        else:
            count[num] = 1

    # 找到出现次数大于等于2的数字，并计算其两位数形式
    for num in count:
        if count[num] >= 2:
            two_digit = int(str(num) + str(num))
            result.append(two_digit)

    return result
