Trigger an Azure Devops pipeline from an azure function using python

I have an existing Devops pipeline that trains ML models. To guaranty the robustness for the models, it will be necessary to retrain it periodically. For this I decided to create an Azure function that will be executed each month. will It collect the new data, apply the data pre-processing and finally trigger the Azure Devops training pipeline. All of this must be done with python. By doing a research, I understood that this can be done using REST Azure Devops API request. I founded this python git repo https://github.com/microsoft/azure-devops-python-api which provides an API to communicate with Azure DevOps. I executed the code provided by this package which displays the list of my devops projects. But I can't found how trigger the pipeline. Assuming that my organisation named ORGA1, the project named PROJ1 and the pipeline that I want ti execute named PIPELINE1, How can I launch it using an Azure function or even a simple python script ? PS: I am using a python 3.9 Timer Trigger Azure function. Thank you in advance for your help.

EDIT

I tired to use LOGIC APP to do this like @mohammed described in the comment and I think that this is a good solution. Above the workflow that I created: enter image description here

So I launch the logic app each X hours, this will trigger the azure Devops, and ASA it end training with Success it will send me an email. I have one error here, is that I am creating a new release and not triggering a specific pipeline each time. But navigating in the different actions under the devops service, I cannot found any thing related to launching a devops pipeline. Can anyone have an idea how to do it.

Thanks to the tips provided by @Mohammed I found a solution. Logic App provides what I am looking for. Under the list of Devops connectors provided the by the Logic App, there is a connector named Queue a new build and this is exactly what I am looking for. This is my first experiment architecture and I will update it later by adding Azure Function service before calling the Devops Pipeline. enter image description here

You may try using Azure Durable Functions, you can kind of replicate what a Logic App does while still using Azure Functions. See documentation here 1

You can use a Logic App with a timer to trigger your DevOps pipeline instead of an Azure function, as it has all the built-in connectors required to interface with your DevOps. See : https://www.serverlessnotes.com/docs/keep-your-team-connected-using-azure-devops-and-azure-logic-apps
