Environment - PyCharm

I am using the below command to get the JSON file:-

aws rds describe-db-cluster-snapshots > snapshotdetails.json

I am using this Json file to extract some data. I want the above command to run from my Python script. I have tried below but its failing:-

from subprocess import call
call(["aws rds describe-db-cluster-snapshots > snapshotdetails.json"])

I am getting error and its not working. Any pointers??

  • @JohnMiliter: you mean to say i need to use below – Prashast May 8 '18 at 22:01
  • call(["aws", "rds", "describe-db-cluster-snapshots" > snapshotdetails.txt"]) – Prashast May 8 '18 at 22:02
  • call(["aws", "rds", "describe-db-cluster-snapshots", ">snapshotdetails.txt"]) -- used this , but getting error "Unknown options: >snapshotdetails.txt" – Prashast May 8 '18 at 22:03

A python3 solution:

from subprocess import Popen, PIPE
cmd_output = Popen(["echo", "foo"], stdout=PIPE)
with open('bar.txt', 'w') as out_handle:
