我可以使用什么数据结构

I have a dump of system usage in a raw txt file. I would like to get it in this format. location, server, usage.

我在原始txt文件中转储了系统用法。我想以这种格式得到它。位置，服务器，用法。

I was looking into a dictionary, but I have multiple locations which will be the key. Unless there is a way to store multiple elements with the same key, I dont see how a dictionary will work. I will be doing this in python. What structure can I use to get my result in this format.

我正在查看字典，但我有多个位置，这将是关键。除非有一种方法来存储具有相同键的多个元素，否则我不会看到字典如何工作。我将在python中执行此操作。我可以使用什么结构来获得此格式的结果。

Ultimately I would like to print all servers in location X

最后，我想打印位置X中的所有服务器

So will have for ex:

所以将有前者：

location1
  server1
     usage X
location1
   server2
      usage X
location2
    server1
      usage x

You can still use dictionary where locations are keys and servers are values containing usages.

您仍然可以使用字典，其中位置是键，服务器是包含用法的值。

>>> locations = collections.defaultdict(dict)
>>> locations['location1']['server1'] = 10000156567
>>> locations['location1']['server2'] = 10000453453
>>> locations['location2']['server1'] = 10000866646
{'location2': {'server1': 10000866646}, 'location1': {'server1': 10000156567, 'server2': 10000453453}}

This basic structure should work for you:

这个基本结构应该适合你：

# list of tuples to store the data
list = [("l1", "s1", "u1"), ("l1", "s2", "u2"), ("l2", "s3", "u1"), ("l2", "s4", "u2"), ("l3", "s5", "u2")]

# find server by location
result = []
for location, server, usage in list:
    if location == "l2":
        result.append((location, server, usage))

print result

# find server by usage
result = []
for location, server, usage in list:
    if usage == "u2":
        result.append((location, server, usage))

print result
