Question

这是eventful.py文件。我使用它来搜索事件并将搜索结果存储在数据库中，但是我很难遍历所有页面，因为搜索结果限制为每页100个结果，而且我不知道如何获取所有结果结果。

            except ValueError:
                raise APIError("Unable to parse API response!")
        elif status == 404:
            raise APIError("Method not found: %s" % method)
        else:
            raise APIError("Non-200 HTTP response status: %s" % response['status'])

如何浏览所有页码？当前，页码是在事件文件中通过args ['page_number'] = 1定义的，我想遍历所有页码吗？是否可以通过循环循环访问页码，直到page_number为false为止？

import eventful

api = eventful.API('KEY_HERE')

events = api.call('/events/search', q='', l='New York', c='music', t='This Week')


for event in events['events']['event']:
        print(event['image'])

遍历具有多个页面的API
