请为pandas数据帧建议一个结构

时间：2016-12-02 05:58:51

标签： python json pandas dictionary scikit-learn

我有很多json文件，格式如下。我想将它们全部加载到一个pandas数据帧中，我计划绘制直方图，绘图，进行算术运算，甚至用scikit学习进行一些聚类。你能否建议一种方法来加载所有这些，以及数据框架的结构，这将使我能够完成我提到的所有内容？它们都有相同的二十个键。

一：我是Pandas的新手，所以如果你评论下面写的代码来帮助我理解你做了什么，我将不胜感激。顺便说一句，我打印出数据帧，它看起来并不具有吸引力。

二：我最终选择了一种字典格式来输出我的数据以保存所有信息，现在就像这样：

文件名是键，值是所有残基的字典作为键和每个的一些数字的列表。然后我可以加载所有这些json文件并使用update（）将它们全部加入一个大字典中。如何改变你在那里写下的代码？

3 个答案:

答案 0 :(得分：0)

假设data是您示例中的词典列表，我会这样做：

pd.DataFrame([pd.DataFrame(dict([(x,pd.Series(y)) 
    for x,y in line.items()])).unstack().dropna() 
              for line in data]).T

框架如下所示：

#                 0           1
#ALA 0     7.000710   59.530941
#    1    13.654881   81.746681
#    2          NaN   88.223732
#    3          NaN   30.139622

#    2   125.168533   45.386559
#... .   ..........   .........

列名是原始JSON中的行索引。

让我们打破这个json， 假设你有一个json文件temp2.​​json

现在您可以使用以下方法将其加载到数据框中：

import json
import pandas as pd

# Reading the json as a dict
with open('temp2.json') as json_data:
    data = json.load(json_data)

df = pd.DataFrame.from_dict(data, orient='index').T

希望这有帮助

让我们编写一个代码来填充数据框

import pandas as pd
import simplejson as json

#this will merge all the json into one DataFrame
df = pd.DataFrame({})
lines = tuple(open('temp.json', 'r'))
lines = ' '.join(map(str,lines))
line = lines.split('\n')
for l in line:
    data = json.loads(l)
    curr_df = pd.DataFrame.from_dict(data, orient='index').T
    df = pd.concat([df,curr_df])
df = df.reset_index()

#Print average
df['ARG'].mean()

#plot histogram
df['ARG'].hist()
