如何在对pandas数据帧进行归一化后保持其索引。json

5

我使用json loads函数获取了一个json对象。然后我创建了一个pd df。现在我需要规范化很多隐藏在唯一列 ['open'] 中的嵌套信息，但是我想保留原始索引，该索引包含我的订单ID。

以下是json数据：

这是作为df的JSON信息

这是我到目前为止使用的代码。

data = json.loads(subprocess.check_output('python -m krakenapi OpenOrders'))
df = pd.DataFrame(data['result'])
df2 = pd.json_normalize(df['open'])

但现在我丢失了订单ID

我尝试过多种方法来立即规范化，但最终我会得到一些看起来奇怪的数据框

我真的需要“只是”得到一个包含所有列在['result']，['open']中的数据框，同时保留最初创建的数据框的原始索引。包含所有我的订单ID的索引。然后它不再需要是索引。它可以存储在一列中，但我确实需要知道正确的ID固定在正确的订单上。我想这显而易见。

编辑：我也尝试了像这样的东西 df = pd.DataFrame（data ['result']，index = id_set [:，2:5]）

df2 = pd.json_normalize(df ['open']，index =) 但是所有这些都没有成功，因为它是意外的参数或字符串对象没有值

import pandas as pd

# get fields of interest 
open_results = data["result"]["open"]

# store nested dictionary as (key1,(k11,k12,13,..k1n))
df = pd.DataFrame.from_dict(open_results, orient='index')

# flatten index to have a flatten dataset (key1,k11,k12,13,..k1n)
df = df.reset_index().rename(columns={"index": "id"})

# Note: the field "descr" is a nested dictionary, you might want to flatten that one too.
# However this is currently out of the scope of the question.

编辑：将“descr”字段展平并不需要太大的努力，以下是代码：

import pandas as pd

# get fields of interest
open_results = json_dict["result"]["open"]

# flatten description fields
for main_key, main_val in open_results.items():
    group = open_results[main_key]
    for key, val in group["descr"].items():
        group.update({key: val})
    group.pop("descr", None)

# store nested dictionary as (key1,(k11,k12,13,..k1n))
df = pd.DataFrame.from_dict(open_results, orient='index')
# flatten index to have a flatten dataset (key1,k11,k12,13,..k1n)
df = df.reset_index().rename(columns={"index": "id"})

输出：

非常感谢，我还没有完全理解这些内容，所以我会稍后尝试。我现在已经从索引创建了一列。df1 = df.rename_axis('txid').reset_index() 但是我仍然无法将其规范化，因为关键字txid没有值...我会尝试理解你在这里做了什么！ - duhh

我还没有完全理解它，但它似乎像PyCharm一样工作。哈哈，谢谢!!! - duhh

好的，不客气。祝你在项目中好运！ - pguardati

我所使用的是：

df = pd.DataFrame(data['result'])
df2 = (
    pd.json_normalize(df['open'])
    .set_index(df.index)
)

然而，就像你一样，我也在寻找一种更简单的方法来设置索引。
