我正在使用Twitter的流媒体API来使用Tweepy提取推文并将它们写入到json文件中。到目前为止,我已经成功地提取了推文,并使用file write
将它们写入了一个json文件,但是当我尝试使用json package
时,我收到了以下代码中提到的错误。字典json在循环python
def on_data(self, data):
#to convert data to dict format since twitter data is in string format
json_data = json.loads(data)
try:
with open('twitter_data.json','ab') as f:
if 'limit' in json_data.keys():
return True
else:
#This method works
#f.write(json.dumps(json_data)+ "\n")
#this one does not as it concatenates dict i.e different dict are not separated by a comma
json.dump(json_data,f)
return True
except BaseException as e:
print e
logging.debug('Error %s',e)
return True
