当需要合并具有重复键的字典列表时，将迭代字符串的键，并根据条件确定结果。

示例

下面是相同的演示

my_list_1 = [{"aba": 1, "best": 4}, {"python": 10, "fun": 15}, {"scala": "fun"}]

my_list_2 = [{"scala": 6}, {"python": 3, "best": 10}, {"java": 1}]

print("The first list is : ")
print(my_list_1)
print("The second list is : ")
print(my_list_2)
for i in range(0, len(my_list_1)):

   id_keys = list(my_list_1[i].keys())
   for key in my_list_2[i]:

      if key not in id_keys:
         my_list_1[i][key] = my_list_2[i][key]

print("结果为: " )
print(my_list_1)

输出

The first list is :
[{'aba': 1, 'best': 4}, {'python': 10, 'fun': 15}, {'scala': 'fun'}]
The second list is :
[{'scala': 6}, {'python': 3, 'best': 10}, {'java': 1}]
结果为:
[{'aba': 1, 'best': 4, 'scala': 6}, {'python': 10, 'fun': 15, 'best': 10}, {'scala': 'fun', 'java': 1}]
