Set Folder Path base on Machine Hostname in Python

Question

I'm trying to make a simple if-check in python. I check for a certain hostname and set path accordingly.

But the result is unexplainable to me.

hostname = os.system('hostname')

if(hostname == 'rkim'):
    path = '/home/forge/rkim-web-app/'
    # This block of code should be running 
else:
    path = '/Applications/MAMP/htdocs/code/rkim-web-app/'
    # But this block of code run instead

Result :

python /home/forge/rkim-web-app/database/backup_mysql.py

rkim <-------- hostname printed == rkim 

Traceback (most recent call last):
  File "/home/forge/rkim-web-app/database/backup_mysql.py", line 28, in <module>
    file = open(path + '.env', "r")
IOError: [Errno 2] No such file or directory: '/Applications/MAMP/htdocs/code/rkim-web-app/.env'

What did I do wrong ?

From `os.system`'s documentation: "the return value is the exit status of the process" — spectras, Mar 06 '17 at 18:59
@spectras : what is the possible alternative then ? Any suggestions ? — code-8, Mar 06 '17 at 19:00
`/Applications/MAMP/htdocs/code/rkim-web-app/.env` exist on my Mac OS X. — code-8, Mar 06 '17 at 19:12

os.system('command') seems to return exit status but prints the hostname. Instead of os module, use platform module to get the host name.

import platform 
hostname = platform.node()

if(hostname == 'rkim'):
    path = '/home/forge/rkim-web-app/'
else:
    path = '/Applications/MAMP/htdocs/code/rkim-web-app/'

Will I need to install any extra module on my linux machine or Mac OS to use this code ?? – code-8 Mar 06 '17 at 19:11

Also, do you mean `host = platform.node()` ? or `hostname = platform.node()` ? – code-8 Mar 06 '17 at 19:11
