Boto3上传数据的问题

Question

I'm parsing data from a NMEA data on a tcp socket and I have to store it into a S3. once parsed the data I have to create a json file to be stored into the bucket.

      #!/usr/local/bin/python
      import boto3
      import jsoncode



#initialization
client = boto3.client('s3')
bucketS3='mybucket'
keyS3='myfolder/myfile..json'
serverIP='192.168.10.219'
serverPort=3000

[...]

if fields[0]==b'$GPRMC':
print ('cmd $GPRMC received!', file=sys.stderr)
msg={}
msg['Long']=fields[5]
msg['Lat']=fields[3]
msg['Spd']=fields[7]
msg['Hdg']=fields[8]
msg['Date']=timeStamp

json_object = (json.dumps(msg.decode("utf-8"))
client.put_object(Body=json_object, Bucket=bucketS3, Key=keyS3)

But it retuns the error:

File "/home/myaws/awsS3/myscritpt.py", line 78
  client.put_object(Body=json_object, Bucket=bucketS3, Key=keyS3)
       ^
SyntaxError: invalid syntax

Any idea?

This line:

json_object = (json.dumps(msg.decode("utf-8"))

has 3 open brackets "(" but only 2 close brackets ")".

You should remove the bracket at the front:

json_object = json.dumps(msg.decode("utf-8"))
