second_obj = [{"country":'India'}]

如何在python中添加字典数组？

third_obj = [{"name":'sat',"age":20,"country":'India'}]

Answer 1

first_obj= [{"name":"sat","age":20}]
second_obj = [{"country":'India'}]

third_obj = [{**first_obj[0], **second_obj[0]}]
print(third_obj)

输出

[{'name': 'sat', 'country': 'India', 'age': 20}]

Answer 2

假设两个对象的长度始终相同，则可以迭代两个列表并合并字典：

third_obj = []
for a, b in zip(first_obj, second_obj):
   combined_dict = dict(a.items() + b.items()) # merge dictionaries
   third_obj.append(combined_dict)
