@thokalavinod

The samples differ from the Java ones here: https://github.com/GoogleCloudPlatform/java-docs-samples/tree/main/security-command-center/snippets/src/main/java/vtwo/findings

Kindly reconcile python samples to match with Java.

Hi @m-strzelczyk, Can you help me to run the PR for checking any errors in Kokoro. Thankyou

[m-strzelczyk]

We don't have GCLOUD_ORGANIZATION defined for the tests - what should it be?

@Sita04 how do you set the SCC_PROJECT_ORG_ID in Java? @thokalavinod maybe we should use the same name as in java?

@m-strzelczyk We fetch the values from this secret: https://github.com/GoogleCloudPlatform/java-docs-samples/blob/main/.kokoro/tests/run_tests.sh#L84 Kindly help import this secret into this repo.

And yes, @thokalavinod update the env variable names to the same as in Java.
