给定一组数字列表，生成一个分类器，将列表中的数字分为偶数和奇数两类。
[1, 2, 3, 4, 5, 6, 7, 8, 9]
可以使用以下Python代码生成一个分类器，将列表中的数字分为偶数和奇数两类：

```python
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9]

even_numbers = []
odd_numbers = []

for number in numbers:
    if number % 2 == 0:
        even_numbers.append(number)
    else:
        odd_numbers.append(number)

print("Even numbers:", even_numbers)
print("Odd numbers:", odd_numbers)
```

输出为：
```
Even numbers: [2, 4, 6, 8]
Odd numbers: [1, 3, 5, 7, 9]
```
