如何使用循环来获取每个元素？

Question

def get_first_profile_id(service):
    # Use the Analytics service object to get the first profile id.

    # Get a list of all Google Analytics accounts for this user
    accounts = service.management().accounts().list().execute()

    if accounts.get('items'):
        # Get the first Google Analytics account.
        account = accounts.get('items')[0].get('id')

        # Get a list of all the properties for the first account.
        properties = service.management().webproperties().list(
                accountId=account).execute()

        if properties.get('items'):
            # Get the first property id.
            property = properties.get('items')[0].get('id')

            # Get a list of all views (profiles) for the first property.
            profiles = service.management().profiles().list(
                    accountId=account,
                    webPropertyId=property).execute()

            if profiles.get('items'):
                # return the first view (profile) id.
                return profiles.get('items')[0].get('id')

    return None

大家好，我正在使用 Google Analytics API 通过 Python 提取数据。以上是谷歌提供的示例代码。

我想使用循环从每个帐户下的每个属性中提取每个“视图（配置文件）ID”。但是，上面的代码只提取了第一个帐户的第一个属性的第一个视图（配置文件）ID。

你能分享一些建议吗？感谢您的帮助！

Answer 1

为 xxx.get('items')[0] 添加 for loop 以循环访问帐户/属性/配置文件中的所有项目。将配置文件附加到列表中，并在所有循环后返回结果。

def get_first_profile_id(service):
    # Use the Analytics service object to get the first profile id.

    # Get a list of all Google Analytics accounts for the authorized user.
    accounts = service.management().accounts().list().execute()

    if accounts.get('items'):
        result = []
        # Loop through Google Analytics account.
        for account_item in  accounts.get('items'):
            account = account_item.get('id')
            # Get a list of all the properties for the account.
            properties = service.management().webproperties().list(
                accountId=account).execute()

            if properties.get('items'):
                # Loop through property id.
                for property_item in  properties.get('items'):
                    property = property_item.get('id')

                    # Get a list of all views (profiles) for the property.
                    profiles = service.management().profiles().list(
                        accountId=account,
                        webPropertyId=property).execute()

                    if profiles.get('items'):
                        # append all view (profile) id in result list.
                        for profile_item in profiles.get('items'):
                            result.append(profile_item.get('id'))
        return result
    return None

Answer 2

替换

if profiles.get('items'):
 # return the first view (profile) id.    
    return profiles.get('items')[0].get('id')

与

if profiles.get('items'):
 # return the first view (profile) id.    
    return [x.get('id') for x in profiles.get('items')]

Answer 3

我还想为初学者提供一个更具可读性的解决方案（不使用列表理解）。

if profiles.get('items'):
    result = [] 
    for profile in profiles.get('items'):
        result.append(profile.get('id'))
    return result
