I am trying to parse the output a command which is in JSON format and running into below error?I provided a sample output of the command aswell,any pointers on how to fix it?

import subprocess,json
user = 'user1'
gerrit = '1234567'
branch_cmd = "ssh -l %s -p 29418 review-android.quicinc.com gerrit query %s --format=JSON"%(user,gerrit)
proc = subprocess.Popen(branch_cmd.split(' '), stdout=subprocess.PIPE, stderr=subprocess.PIPE)
(output, error) = proc.communicate()
print output["branch"]

OUTPUT:-

Need to convert the string into json, like the following:

for line in output.split('\n'):
    print json.loads(line)

To access the first one:

line1 = output.split('\n')[0]
print json.loads(line)["branch"]
