文件numbers.txt中每个数字各占一行，内容如下：

5
12
7
15
3
20
8

执行以下Python代码后，输出结果是：

def func(file_path, threshold):
    lst = []
    with open(file_path) as file:
        for line in file:
            number = int(line.strip())
            if number > threshold:
                lst.append(number)
        return lst
file_path = 'numbers.txt'
threshold = 12
selected_numbers = func(file_path, threshold)
print(selected_numbers)
