在Python中用冒泡排序实现一个从小到大排列的列表。
numbers = [7, 3, 15, 1, 9, 0, 13]
下面是实现：

```
numbers = [7, 3, 15, 1, 9, 0, 13]
n = len(numbers)

for i in range(n):
    for j in range(0, n-i-1):
        if numbers[j] > numbers[j+1]:
            numbers[j], numbers[j+1] = numbers[j+1], numbers[j]

print(numbers)
```

输出结果：
```
[0, 1, 3, 7, 9, 13, 15]
```
