Question

我有以下表格的数据：

{'count': '274',  'file_type': 'json', 'limit': '100000',    observation_end': '9999-12-31',    'observation_start': '1776-07-04',    'observations': "[{'date': '1947-01-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '3.962'}, {'date': '1947-04-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '4.052'}, {'date': '1947-07-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '4.172'}, {'date': '1947-10-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '4.270'}, {'date': '1948-01-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '4.372'}, {'date': '1948-04-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '4.432'}, {'date': '1948-07-01', 'realtime_start': '2015-08-20', 'realtime_end': '2015-08-20', 'value': '4.521'}]

我想从中创建CSV或Excel文件，以便在不同的行上显示不同的值。例如数据1948-07-01价值4521.是否可能以及如何？我试过以下：

writer = csv.writer(open('dict.csv', 'wb'))
for key, value in mydict.items():
    writer.writerow([key, value])

但最后一行包含单行列表中的所有词典。

Answer 1

import ast # since your observations seems to be a string 
a=your_dictionary
observations=ast.literal_eval(a["observations"]) # this will convert this string to list
headers=observations[0].keys() 
writer = csv.writer(open('dict.csv', 'wb'))
writer.writerow(headers) # to make sure your headings are date,realtime_start etc
for data in observations:
    row=[data[header] for header in headers] #will create the row in same order as headers
    writer.writerow(row)

Answer 2

您必须首先使用键编写标题，然后编写您的值。

鉴于您的所有数据都具有相同的密钥，以下内容将起作用：

collections.OrderedDict

请务必使用.keys确保.values和using UnityEngine; using System.Collections; public class LoadingScreen : MonoBehaviour { public string levelToLoad; public GameObject background; public GameObject text; public GameObject progressBar; private int loadProgress = 0; // Use this for initialization void Start () { background.SetActive (false); text.SetActive (false); progressBar.SetActive (false); } // Update is called once per frame void Update () { if (Input.GetKeyDown ("space")) { StartCoroutine(DisplayLoadingScreen(levelToLoad)); } } IEnumerator DisplayLoadingScreen(string level){ background.SetActive (true); text.SetActive (true); progressBar.SetActive (true); progressBar.transform.localScale = new Vector3(loadProgress,progressBar.transform.localScale.y, progressBar.transform.localScale.z); text.GetComponent<GUIText>().text = "Loading Progress " + loadProgress + "%"; AsyncOperation async = Application.LoadLevelAsync (level); while (!async.isDone) { loadProgress = (int)(async.progress * 100); text.GetComponent<GUIText>().text = "Loading Progress " + loadProgress + "%"; progressBar.transform.localScale = new Vector3(async.progress,progressBar.transform.localScale.y, progressBar.transform.localScale.z); yield return null; } }方法以相同的顺序返回项目。

Python中包含多个词典的列表中的CSV文件？
