Executing AWS CLI using python

Question

While Executing AWS CLI using python, Please find code for reference.

import awscli.clidriver
driver = awscli.clidriver.create_clidriver()
driver.main(['ec2','describe-instances','--instance-ids','i-12345678'])

Is it possible to store the output of driver.main in a variable ?

I don't think this is supported by the AWS CLI but you can do this:

import awscli.clidriver
from cStringIO import StringIO
import sys

driver = awscli.clidriver.create_clidriver()

old_stdout = sys.stdout
sys.stdout = mystdout = StringIO()

driver.main(['ec2','describe-instances','--instance-ids','i-12345678'])

sys.stdout = old_stdout

myvar = mystdout.getvalue()

Note that this is based on another Stack Overflow answer here.

Thanks for help. yes its returning the expected outcome, but result is string and is not convertible to json using json library of python. – Sakshi Gupta Dec 03 '18 at 12:26
Of course it is convertible to JSON. Just add lines `import json ; myjson = json.loads(myvar)`. – Alex Harvey Dec 03 '18 at 13:22
@SakshiGupta, if this helped you should accept the correct answer. – Alex Harvey Feb 05 '19 at 03:03
