Passing a parameter into AWS CLI command

I'm trying to set tags on an EC2 instance with the following call from a python script where I am passing in a variable instanceId as the resource to add the tags on:

subprocess.call('aws ec2 create-tags --resources $instanceId --tags "Key=somekey, Value=someval"')

But I get this error:

An error occurred (MissingParameter) when calling the CreateTags operation: The request must contain the parameter resourceIdSet
255

However, when I print out instanceId, I see the correct id of the instance so there must be something wrong with the way I am passing in the variable. Is there a different convention for this?

Your variable $instanceId in your AWS CLI command will end up being a shell variable, and won't be substituted from your Python code.

So, if $instanceId is a Python variable, you may need to do something like:

subprocess.call('aws ec2 create-tags --resources ' + $instanceId  + ' --tags "Key=somekey, Value=someval"')

Note: I am not a Python developer, so this is a stab in the dark.
