Python 2.7-在比较字典时仅显示修改后的字典键/值 [英] Python 2.7 - Show only modified dictionary key/value while comparing dictionaries

问题描述

尝试使用此代码比较两个字典:

Trying to compare two dictionaries with this code:

def dict_compare(d1, d2):
    d1_keys = set(d1.keys())
    d2_keys = set(d2.keys())
    intersect_keys = d1_keys.intersection(d2_keys)
    added = d1_keys - d2_keys
    removed = d2_keys - d1_keys
    modified = {o: (d1[o], d2[o]) for o in intersect_keys if d1[o] != d2[o]}
    same = set(o for o in intersect_keys if d1[o] == d2[o])
    return added, removed, modified, same

one = {"1iG5NDGVre": {"118": ["test1", "test2", "test3", "tcp", "22", "Red", "0.0.0.0/0"]}}
two = {"1iG5NDGVre": {"118": ["test1", "test2", "test3", "tcp", "22", "Red", "Blue", "0.0.0.0/0"]}}

added, removed, modified, same = dict_compare(one,two)

print added
print removed
print modified
print same

但是，它会错误地打印修改后的键/值.

However, it prints the modified key/values wrongly.

输出:

set([])
set([])
{'1iG5NDGVre': ({'118': ['test1', 'test2', 'test3', 'tcp', '22', 'Red', '0.0.0.0/0']}, {'118': ['test1', 'test2', 'test3', 'tcp', '22', 'Red', 'Blue', '0.0.0.0/0']})}
set([])

有什么办法纠正它吗?

我只希望它在修改后显示蓝色".

I just want that it prints "Blue" in modified.

更新1:

有效，但当字典具有不同的键号时无效，即

Works but not when the dicts have different keys number i.e

one = {"1iG5NDGVre": {"118": ["test1", "test2", "test3", "tcp", "22", "Red", "0.0.0.0/0"]}}
two = {"1iG5NDGVre": {"118": ["test1", "test2", "test3", "tcp", "22", "Red", "Blue", "0.0.0.0/0"]},"119": ["test10","test11"]}

不会显示已添加的test10和test11.

Will not show up test10 and test11 as added.

字典也可以有更少的键，也可以删除键.还要涵盖这种情况.

Dict could also have less keys, key can be also removed. Want to also cover that case.

非常感谢！

推荐答案

您应该使用按位互斥或(^)将列表与实际值进行比较:

You should compare the list with the actual values with a bitwise exclusive or (^):

differences = set(one["1iG5NDGVre"]["118"]) ^ set(two["1iG5NDGVre"]["118"])
print differences
