Below is the final code:

import requests, json, sys

r = requests.get('http://napmongo01.cvc.com.br:28017/_status')
j = r.json()

arg = sys.argv[1]

}

for command in commands:
    if arg in commands:
        print commands[command]
    else:
        print 'Invalid command'


Below the output:
(danilochilene at notebico - ~/lixo @14:06:56)
2: python mongo-test.py uptime
j['serverStatus']['uptime']

(danilochilene at notebico - ~/lixo @14:07:00)
2: python -i mongo-test.py uptime
j['serverStatus']['uptime']
>>> j['serverStatus']['uptime']
27806
>>>

My only issue now is commands[command] (as the example above) have the same
output as j['serverStatus']['uptime'].

Thanks for the help so far!
