Syntax Problem

I have a Python script I am trying to run.

import commands
cmd = 'gpio read 1'
output = commands.getoutput(cmd)

if commands.getoutput(cmd) == 0:
   print ('The door is closed.')

When I run it, nothing happens. It just goes to the next line instead of printing.

Any idea what I am doing wrong?

What are you trying to get it to do? commands.getoutput(cmd) is returning a non-zero value. What are you wanting it to return?

This is on a raspberry pi. It should return a value of 1 or 0.

So it is returning 1.

Yes, it will return 1 when the door is open. Am I writing the condition statement wrong?

When type gpio read 1 at the console it outputs 0 if the door is closed and 1 if it is opened

I found a script and was able to modify it to get what I want, is it okay with you if I post it here with my question or should I close this out and open another question?

Technically, you should start a new question if it is a different issue. That's a better way to get more eyes on the issue anyway.

I see the actual problem now that I saw the other script. You should have been checking if it was == to "0" instead of 0. But I think you see that now too.
