有没有办法将一个字典的元素附加到另一个

Question

我需要将字典值附加到已经存在的JSON文件中。我怎么能够 能够做到这一点？

我的details.json文件

{"name": "someName"}

我的python脚本生成的字典

list1 = {"name": "someOthername"}

with open("details.json") as r:
    data = json.load(r)
    desirableDict = data.append(list1) # It has to be something like this
    print(desirableDict)

理想的输出：     {“ name”：“ someName”，“ someOthername”}
