Question

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，用途。

我正在查找字典，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这种格式的结果。

最终我想打印位置X的所有服务器

对于前者也是如此：

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

Answer 1

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}}

Answer 2

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

我可以使用哪种数据结构
