Write a python script to create a infinite loop using for ?

Question

I'm trying to write a python script that writes some content to a file root through sudo, but it's not working at all. I am using:

 channel = 'stable'
 config_file = '/opt/ldg/etc/channel.conf'
 command = ['echo', '-n', channel, '|', 'sudo', 'tee', config_file]
 p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
 out, _ = p.communicate()

But it seems as if this isn't doing anything.

I just want to write the contents of the variable channel to the file /opt/ldg/etc/channel.conf. But whatever I try just doesn't work. Can anyone offer any pointers?

Try something like following

while True: 
    print 'QueryHome'

for x in iter(int, 1):
    print 'QueryHome'

what is iter(int,1)?

These are two method anyone you can choose to achieve the infinite loop. Documentation of built-in functions can be found at https://docs.python.org/2/library/functions.html
