Python 通过创建新图形来更改图形

我正在做一个图表，它代表了迷宫中的所有动作。事情是在复制我重复的动作时，所以我的字典的输出如下：

{1,2:[2,2]

3,2:[4,2,3,3,2,2],

3,3:[3,2,3,4]

5,2:[5,3,4,2]

4,4:[5,4,3,4]

5,4:[5,3,4,4]

2,2:[3,2,1,2]

4,2:[5,2,3,2]

3,4:[4,4,3,3]

5,3:[5,2,5,4]}

你知道我如何在旧字典的基础上编一本新字典，以及如何消除重复的动作吗

编辑：这本词典只是一个例子。

一种方法是：

# Here's your node collection
toclean = {(1, 2): [(2, 2)],
(3, 2): [(4, 2), (3, 3), (2, 2)],
(3, 3): [(3, 2), (3, 4)],
(5, 2): [(5, 3), (4, 2)],
(4, 4): [(5, 4), (3, 4)],
(5, 4): [(5, 3), (4, 4)],
(2, 2): [(3, 2), (1, 2)],
(4, 2): [(5, 2), (3, 2)],
(3, 4): [(4, 4), (3, 3)],
(5, 3): [(5, 2), (5, 4)]}

# Here is a place to store nodes we've already seen
seen = set()

# Here is your new collection
result = {}

# Iterate over the original collection in sorted node order
for key, values in sorted(toclean.items()):
    # Mark node as seen
    seen.add(key)
    # Link it to any node that wasn't seen before
    result[key] = [val for val in values if val not in seen]

print result

{(1, 2): [(2, 2)],
 (2, 2): [(3, 2)],
 (3, 2): [(4, 2), (3, 3)],
 (3, 3): [(3, 4)],
 (3, 4): [(4, 4)],
 (4, 2): [(5, 2)],
 (4, 4): [(5, 4)],
 (5, 2): [(5, 3)],
 (5, 3): [(5, 4)],
 (5, 4): []}

但我想看看如何生成图形：过滤效果更好
