Python循环获取的多个json文件数据，数据拼接不到一个列表中？

Python循环获取的多个json文件数据，数据怎么拼接不到一个列表中，代码如下：
dict_1是从多个json文件中获取的多个字典

value_3 = []
    for k2, v2 in dict_1.items():
        if v2:
            if '05TF4095116113' in v2['defectCode']:
                value_3.append(k2)
                print(value_3)

输出：

['03120AA113CF413C897A84014259ABF0']
['1BF1778E39D34FB98EBB6D34422B0078']
['1D6837E19B454A3BAB0400520C43E2EB']
['1D6837E19B454A3BAB0400520C43E2EB']
['1D6837E19B454A3BAB0400520C43E2EB']
['6E390A103A3D4885A624FE1C560B91D5']
['6E390A103A3D4885A624FE1C560B91D5']
['6E390A103A3D4885A624FE1C560B91D5']

该回答引用chatgpt:

dict_1 = {}  # 假设这是从多个json文件中获取的多个字典

value_3 = []
for k2, v2 in dict_1.items():
    if v2 and 'defectCode' in v2 and '05TF4095116113' in v2['defectCode']:
        value_3.append(k2)

print(value_3)
