Question

我是Python的新手，我正在尝试将我的字典内容称为python_diction（位于更大的文件中）并将该数据保存到一个名为python_diction_saved.json的新文件中。我觉得我非常接近我目前收到的错误python_diction_saved.json未定义。

非常感谢任何帮助。

import json
f = open("python_diction.txt","w")
python_diction = {}
python_diction["items"] = []
python_diction["items"].append({"hello":1,"hi":2})
python_diction["items"].append({"hello":42,"hi":65})
python_diction["numbers"] = [1,2,3,5,7,8]
f.write(json.dumps(python_diction_saved.json))
f.close()

为了将python_diction写入名为python_diction_saved.json的文件，您可以使用json.dump（以避免必须自己编写）：

import json
python_diction = {}
python_diction["items"] = []
python_diction["items"].append({"hello":1,"hi":2})
python_diction["items"].append({"hello":42,"hi":65})
python_diction["numbers"] = [1,2,3,5,7,8]

with open("python_diction_saved.json") as output_file:
    json.dump(python_diction, output_file)

将字典保存到文件
