在数组列表中显示偶数和奇数时出现问题

def separate_even_odd(numbers):
    if not numbers:  # 检查数组是否为空
        return [], []
    
    even_numbers = []
    odd_numbers = []
    
    for num in numbers:
        if isinstance(num, int):  # 确保元素是整数
            if num % 2 == 0:
                even_numbers.append(num)
            else:
                odd_numbers.append(num)
        else:
            print(f"Warning: {num} is not an integer and will be ignored.")
    
    return even_numbers, odd_numbers

# 示例使用
numbers = [1, 2, 3, 4, 5, 'a', 6]
even_nums, odd_nums = separate_even_odd(numbers)
print("Even numbers:", even_nums)
print("Odd numbers:", odd_nums)
