Python 操作以字符串形式存储的CSV数据

我有一个API字符串，它以XML页面响应，并将我的数据作为CSV存储在数据标记中。我可以以JSON格式请求它，但我无法以该格式在Python脚本中正确处理数据

首先，我希望通过引用数据标记的名称来存储数据标记中的文本，但我目前仅通过使用以下方法获得了成功：

response = requests.get(url)
root = ElementTree.fromstring(response.content)

dataString = root[6].text

是否有单独的命令可以指定标记的名称

接下来，我的目标是遍历对应于不同帐户的不同URL，并将这些帐户的名称附加到数据的末尾。如果数据存储为字符串，并且我需要将其添加到每行的末尾，那么这可能吗？接下来，在变量中保存多个值以便能够循环（即帐户列表）的最佳约定是什么

抱歉，如果不清楚，我很乐意提供更多信息，如果这意味着任何人都可以提供帮助。

据我所知，您为每个用户都有一个特定的URL，并且您希望为给定的所有用户收集数据

但是，由于您无法从响应中获取用户名，因此必须将响应与发送请求的URL对应的用户名结合起来。如果是这样，您可以使用字典来存储响应的数据，因为JSON格式与Python的字典是等效的

下面的代码只是在包含不同用户名和相应URL的列表中进行迭代。对于每个发送请求的URL，数据都从JSON格式的响应中提取出来，并以用户名作为密钥存储在URL中。然后，该词典存储在一种主词典中，其中包含所有收集的数据集

# replace names 'url_xyz' with corresponding names and url
users = {('Albert', 'url_albert'), ('Steven', 'url_steven'), ('Mike', 'url_mike')}

all_data = dict()

for name, url in users:
    response = requests.get(url)
    data = response['data'].replace('\"', '')
    all_data.update({name: data})

谢谢你，艾伯特

您的JSON建议让我能够更好地控制数据。下面的代码是我最终获得所需输出的代码。现在，我们来研究一下如何将日期从MM/DD/YYYY转换为DD/MM/YYYY

startDate = '2015-01-01' # Must be in format YYYY-MM-DD
endDate = '2015-12-31' # Must be in format YYYY-MM-DD
dimensions = 'date' # Available dimensions are 'date' and 'cid'
format = 'json'
dataFormat = 'json'
measures = 'initRegistrations,registrations,siteLogins,newUsers'
allData = []

# Construct API URL
for i in range(0,len(apiKey)):

      url = ('https://reports.eu1.gigya.com/reports.getAccountsStats?secret=' + secret + '&apiKey=' + apiKey[i] + \
            '&uid=' + uid + '&startDate=' + startDate + '&endDate=' + endDate + '&dimensions='+ dimensions +\
            '&measures=' + measures + '&format=' + format + '&dataFormat=' + dataFormat)

      response = requests.get(url)

      json = response.json()
      data = json['data']

      if i == 0:
            headers = json['headers']
            headers.append('brand')

            for x in range(0,len(data)):
                  data[x].append(brand[i])

            brandData = [headers] + data
      else:
            for x in range(0,len(data)):
                  data[x].append(brand[i])

            brandData = data

      allData += brandData


with open("testDataJSON.csv", "wb") as f:
      writer = csv.writer(f)
      writer.writerows(allData)

我不知道这在多大程度上符合Python的最佳实践，但正如我所说的，我对它非常陌生。

您是说您还可以将数据格式化为JSON格式。如果是这样，请您使用JSON格式的数据提供代码段？使用JSON格式的响应编辑JSON格式提取数据很容易，因为JSON数据可以像字典一样访问：data=response['data']好的，如果我有这种格式的数据，我需要循环遍历列表中的每个值，并在末尾附加一个额外的字符串以满足按帐户命名的需要？这是我无法理解的一点。你能用一些扩展你的问题的示例片段更详细地描述一下吗？顺便说一句，到目前为止你都尝试了什么？请注意Stackoverflow不是一个论坛，而是一个问答平台。只需重新排列日期和月份的快速字符串方法如下：date='09/01/2015'date_parts=date.split'/'new_date='{}/{}/{}'。formatdate_parts[1]、date_parts[0]、date_parts[2]然而，使用datetime模块有更优雅的方法来实现这一点。

startDate = '2015-01-01' # Must be in format YYYY-MM-DD
endDate = '2015-12-31' # Must be in format YYYY-MM-DD
dimensions = 'date' # Available dimensions are 'date' and 'cid'
format = 'json'
dataFormat = 'json'

            '&measures=' + measures + '&format=' + format + '&dataFormat=' + dataFormat)

      response = requests.get(url)

      json = response.json()
      data = json['data']

      if i == 0:
            headers = json['headers']
            headers.append('brand')

            for x in range(0,len(data)):
                  data[x].append(brand[i])
