Python ValueError：更改值时出现太多无法解压缩的值（预期为2）错误

当我将一个键（如

1234567890

传递到此函数）以向其值中添加一个时

使用

def addUse(key):
    with open ("keys.json") as f:
        data = json.loads(f.read())
        for i, d in data["keys"]:
            if(d["key"] == key):
                d["uses"] = d["uses"] + 1

    with open ("keys.json", "w+") as f:
        json.dump(data,f)

我得到了错误

Traceback (most recent call last):
  File "C:\Users\Jlp02\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "index.py", line 104, in redeem
    await addUse(key)
    for i, d in data["keys"]:
ValueError: too many values to unpack (expected 2)

The above exception was the direct cause of the following exception:

    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ValueError: too many values to unpack (expected 2)

这就是keys.json文件的外观

data.keys（）

For any dictionary返回字典中定义的键的视图

如果要在字典中的键值对上进行迭代，可能需要尝试类似的操作

for key, value in my_dict.items():
    ...

---

我只需删除中的

i

for i, d in data["keys"]:
            if(d["key"] == key):
                d["uses"] = d["uses"] + 1

是的

for d in data["keys"]:
            if(d["key"] == key):
                d["uses"] = d["uses"] + 1

---

用于数据[“键”]中的i，d

为什么<代码>数据[“键”]是一个

列表

请用完整的错误回溯更新您的问题。

my_dict.keys（）

？是不是

items（）

？哈哈，谢谢@deadshot，看起来我5分钟都无法集中注意力：p
