additionally, if use append mode of file writing instead of write method can continuously output.

scrapy uses concept of pipelines allow lot of same functionality. here's example of scrapy code might use same thing:

class jsonwriterpipeline(object):     def __init__(self):         self.file = (open(filepath, 'a'))     def process_item(self, item, spider):         self.file.write(json.dumps(dict(item)) + '\n')         return item
