首先，我是 Julia 的新手，所以我还在适应这门语言。

我正在使用 Jupyter，并且正在尝试添加“SpecialPolynomials”。这是我不断得到的：

using Pkg
Pkg.add("SpecialPolynomials")

正在解决算法问题，必须颠倒列表。完成后，我的代码如下所示：

def construct_path_using_dict(previous_nodes, end_node):
    constructed_path = []
    current_node = end_node
    while current_node:
        constructed_path.append(current_node)
        current_node = previous_nodes[current_node]
    constructed_path = reverse(constructed_path)    
    return constructed_path

但是，一路上，我尝试了一下，return constructed_path.reverse()发现它没有返回列表......为什么会这样？
我应该能够直接返回反向列表，而不需要先执行list.reverse()or ，这难道不有意义吗list = reverse(list)？
