How to remove a cloud armor secuiry policy from backend service using Python

I'm creating a few GCP cloud armor policies across multiple projects using the Python client library and attaching them to several backend services using the .set_security_policy() method
I know you can do it using the console / gcloud but I need to automate this in Python
I've tried the .update() method in google-cloud-compute but that did not work out
from google.cloud import compute, compute_v1
client = compute.BackendServicesClient()
backend_service_resource = compute_v1.types.BackendService(security_policy="")
client.update(project='project_id',
backend_service='backend_service',
backend_service_resource=backend_service_resource)
The error I got when running the above code is
google.api_core.exceptions.BadRequest: 400 PUT https://compute.googleapis.com/compute/v1/projects/<project-id>/global/backendServices/<backend-name>: Invalid value for field 'resource.loadBalancingScheme': 'INVALID_LOAD_BALANCING_SCHEME'. Cannot change load balancing scheme.
When I specify loadBalancingScheme then the same error occurs with another resource value. At run-time I would not have information of all the meta data of the backend-service and some meta-data might not be initialized in the first place.

This is for anyone who had similar issues in the future. I was originally going to call the gcloud commands through python using os.system() as #giles-roberts recommended, but then I stumbled across a proper way to to do this using the Client Libraries
You simply use the same .set_security_policy() to set the security policy in the first place but this time make the policy as None. This is not quite obvious since the name of the security policy has to be a string in the documentation and it does not accept an empty string either.
from google.cloud import compute, compute_v1
client = compute.BackendServicesClient()
resource = compute_v1.types.SecurityPolicyReference(security_policy=None)
error = client.set_security_policy(project='<project_id>',
backend_service='<backend_service>',
security_policy_reference_resource=resource)

How to specifify the class of an AWS client in Python?

In Java, for instance, we have a class that represents the SageMaker client class: AmazonSageMakerClient, but I couldn't find the equivalent for Python.
I was hoping to be able to do something like:
from sagemaker import SageMakerClient
client: SageMakerClient = boto3.client("sagemaker")
I looked into the library code and docs but I couldn't find any references to such class containing the defined methods for that client. In fact, I couldn't find any classes for AWS clients like s3, sqs, etc. Are those hidden somewhere or am I missing something obvious?

In boto3, there is basically 2 levels of objects avaialble:
A client
Actual objects like you are asking about
Take a look at S3, and you will see that in addition to the Client object there are also other rich object types like Bucket.
It would seem that Sagemaker doesn't (yet) have this second level of abstraction available.

To be more productive, and work with Python classes rather than Json, try to use the SageMaker Python SDK whenever possible rather than Boto3 clients.
With Boto3 you have several SageMaker clients (As #anon said correctly):
SageMaker - Most of SageMaker features
SageMakerRuntime - Invoking endpoints
SageMaker* - Other misc SageMaker features like feature store, edge manager, ...

The boto3-stubs library can help with this.
Install using the instructions for your IDE on the package page, and then install the specific type annotations for SageMaker.
pip install 'boto3-stubs[sagemaker]'
You should be able to see type hints for the client object (type: SageMakerClient).
import boto3
client = boto3.client('sagemaker')
If you need to add hints yourself:
from mypy_boto3_sagemaker import SageMakerClient
def my_func(client: SageMakerClient):
client.create_algorithm(...)

Python vs. Node.js Event Payloads in Firebase Cloud Functions

I am in the process of writing a Cloud Function for Firebase via the Python option. I am interested in Firebase Realtime Database Triggers; in other words I am willing to listen to events that happen in my Realtime Database.
The Python environment provides the following signature for handling Realtime Database triggers:
def handleEvent(data, context):
# Triggered by a change to a Firebase RTDB reference.
# Args:
# data (dict): The event payload.
# context (google.cloud.functions.Context): Metadata for the event.
This is looking good. The data parameter provides 2 dictionaries; 'data' for notifying the data before the change and 'delta' for the changed bits.
The confusion kicks in when comparing this signature with the Node.js environment. Here is a similar signature from theNode.js world:
exports.handleEvent = functions.database.ref('/path/{objectId}/').onWrite((change, context) => {}
In this signature, the change parameter is pretty powerful and it seems to be of type firebase.database.DataSnapshot. It has nice helper methods such as hasChild() or numChildren() that provide information about the changed object.
The question is: Does Python environment have a similar DataSnapshot object? With Python, do I have to query the database to get the number of children for example? It really isn't clear what Python environment can and can't do.
Related API/Reference/Documentation:
Firebase Realtime DB Triggers: https://cloud.google.com/functions/docs/calling/realtime-database
DataSnapshot Reference: https://firebase.google.com/docs/reference/js/firebase.database.DataSnapshot

The python runtime currently doesn't have a similar object structure. The firebase-functions SDK is actually doing a lot of work for you in creating objects that are easy to consume. Nothing similar is happening in the python environment. You are essentially getting a pretty raw view at the payload of data contained by the event that triggered your function.
If you write Realtime Database triggers for node, not using the Firebase SDK, it will be a similar situation. You'll get a really basic object with properties similar to the python dictionary.
This is the reason why use of firebase-functions along with the Firebase SDK is the preferred environment for writing triggers from Firebase products. The developer experience is superior: it does a bunch of convenient work for you. The downside is that you have to pay for the cost of the Firebase Admin SDK to load and initialize on cold start.
Note that might be possible for you to parse the event and create your own convenience objects using the Firebase Admin SDK for python.

Remove user from a slack team [API]

I need to remove user from slack team (totally), via API using Python. Recently I've found the undocumented methods https://github.com/ErikKalkoken/slackApiDoc
But users.admin.setInactive is not working correctly. It seems that there is no such method, because I get an AttributeError: 'UsersAdmin' object has no attribute 'setInactive'
Is there any way to achieve my goal?

Unfortunately this method is not available for Slack teams that use the free tier, so I can not fully test it. However, I am still getting the error "paid_only" when I call it, which would suggest that the API method itself does exist.
Based on your error it sounds more like in error in the implementation of the access layer to the API (e.g. if you are using 3rd party library it may not include this method).
You can verify by calling the method directly, which should work if you are on a paid tier:
https://slack.com/api/users.admin.setInactive?token=TOKEN&user=U12345678
If that works your issue is in the access layer of your code / the 3rd party library you are using.

How to create Azure Application gateway using python SDK

I'm starting to feel a bit stupid. Have someone been able to successfully create an Application gateway using Python SDK for Azure?
The documentation seems ok, but I'm struggling with finding the right parameters to pass 'parameters' of
azure.mgmt.network.operations.ApplicationGatewaysOperations application_gateways.create_or_update(). I found a complete working example for load_balancer but can't find anything for Application gateway. Getting 'string indices must be integers, not str' doesn't help at all. Any help will be appreciated, Thanks!
Update: Solved. An advice for everyone doing this, look carefully for the type of data required for the Application gateway params

I know there is no Python sample for Application Gateway currently, I apologize for that...
Right now I suggest you to:
Create the Network client using this tutorial or this one
Take a look at this ARM template for Application Gateway. Python parameters will be very close from this JSON. At worst, you can deploy an ARM template using the Python SDK too.
Take a look at the ReadTheDocs page of the create operation, will give you the an idea of what is expected as parameters.
Open an issue on the Github tracker, so you can follow when I do a sample (or at least a unit test you can mimic).
Edit after question in comment:
To get the IP of VM once you have a VM object:
# Gives you the ID if this NIC
nic_id = vm.network_profile.network_interfaces[0].id
# Parse this ID to get the nic name
nic_name = nic_id.split('/')[-1]
# Get the NIC instance
nic = network_client.network_interfaces.get('RG', nic_name)
# Get the actual IP
nic.ip_configurations[0].private_ip_address
Edit:
I finally wrote the sample:
https://github.com/Azure-Samples/network-python-manage-application-gateway
(I work at MS and I'm responsible of the Azure SDK for Python)
