参数： dict1， dict2
需求：如果dict1和dict2中有不同的key，那么返回这个(key， dict1[key])；如果dict1和dict2中有相同的key，但是value不同，返回这个(key， dict1[key])
实现：
def dict_different_data(first, second):
"""
get the different data bewtten two dicts objects
return :result = first - second """
assert isinstance(first, dict)
assert isinstance(second, dict)
different_data = {}
update_key = set(first).intersection(set(second))
insert_key = set(first).difference(set(second))
delet_key = set(second).difference(set(first)) #updata data item which are both on first and second and Not equal values
for k in update_key:
if(isinstance(first[k], dict)):
result = dict_different_data(first[k], second[k])
if len(result) > 0:
different_data[k] = result
elif first[k] != second[k]:
different_data[k] = first[k]
#insert new item from first
for k in insert_key:
different_data[k] = first[k]
#delet data
for k in delet_key :
different_data[k] = None return different_data if __name__ == "__main__":
dic1 = {
'name': 'test',
'score': 89
}
dic2 = {
'name': 'test',
'score': 29,
'age': 23
}
result = dict_different_data(dic2, dic1)
print result
