实际遇到的问题逻辑很繁杂,就不全写了。最后是通过对比两个字典差异来解决的。找出两个字典的差异,可参考以下代码。

dict1 = {'a':1,'b':2,'c':3,'d':4}
dict2 = {'a':1,'b':2,'c':5,'e':6}

differ = set(dict1.items()) ^ set(dict2.items())
print(differ)
#所有差异
#输出:{('c', 3), ('e', 6), ('c', 5), ('d', 4)}
diff = dict1.keys() & dict2

diff_vals = [(k, dict1[k], dict2[k]) for k in diff if dict1[k] != dict2[k]]
print(diff_vals)
#相同key,不同value
#输出:[('c', 3, 5)]

  

其他参考:

a = {
    "x":1,
    "y":2,
    "z":3
}
b = {
    "x":1,
    "w":11,
    "z":12
}
print(a.items())
>>>dict_items([('x', 1), ('y', 2), ('z', 3)])
# 查看两个字典共有的key
print(a.keys() & b.keys())
>>>{'x', 'z'}
# 查看字典a 和字典b 的不共有的key
print(a.keys() ^  b.keys())
>>>{'y'}
# 查看在字典a里面而不在字典b里面的key
print(a.keys() - b.keys())
>>>{('x', 1)}
# 查看字典a和字典b相同的键值对
print(a.items() & b.items())
>>>{'w', 'y'}
