gcloud compute execute command remotely

Question

Currently, if I want to execute something on a VM, I copy files over like this:

gcloud compute --project <project_id> copy-files --zone <zone_name> /home/roman/source/dir roman@<vm_name>:/some/path 

Then I need to SSH into it manually like this:

gcloud compute --project <project_id> ssh --zone <zone_name> <vm_name> 

And then go and run some command:

cd /some/path python example.py 

How do I combine step 2 and 3 together and execute a command remotely?

Note: I want to use gcloud or the python api. I don't want to use 3rd party packages like Fabric.

Try:

$ gcloud compute ssh --zone ZONE INSTANCE -- 'cd /tmp && python some.py' 

From gcloud compute ssh --help:

 [-- IMPLEMENTATION-ARGS ...]     Flags and positionals passed to the underlying ssh implementation.      The '--' argument must be specified between gcloud specific args on the     left and IMPLEMENTATION-ARGS on the right. Example:          $ gcloud compute ssh example-instance --zone us-central1-a -- -vvv \             -L 80:%INSTANCE%:80
