Inline PythonScript Azure Pipelines task in external file - azure-devops

Question

I am developing a Azure task template, and I have a large .py file that I want to be executed in one step
- task: PythonScript#0
displayName: 'Run a Python script'
inputs:
scriptSource: inline
script: |
... really long python code
It's possible to store the code in another file, at the same level of the yml template, and consume it from there? Or what would be the best approach to keep the template clean?
I know that it's possible to use scriptSource
- task: PythonScript#0
displayName: 'Run a Python script'
inputs:
scriptSource: 'filePath'
scriptPath: 'my_python.py'
arguments: '${{ parameters.my_param }}'
But as the template is in another repository than the repository ran in the pipeline, I don't think that I can reach that my_python.py without downloading it with a wget, or cloning, or doing additional steps. I am right?
Regards!

To use a template from another repo you need to define repository source like here:
# Repo: Contoso/LinuxProduct
# File: azure-pipelines.yml
resources:
repositories:
- repository: templates
type: github
name: Contoso/BuildTemplates
steps:
- template: common.yml#templates # Template reference
Once you have you need to just checkout this repo:
# Repo: Contoso/LinuxProduct
# File: azure-pipelines.yml
resources:
repositories:
- repository: templates
type: github
name: Contoso/BuildTemplates
steps:
- checkout: self
- checkout: templates #this download whole repo
- template: common.yml#templates # Template reference
Now you need to figure out where it is downloaded ;)
Multiple repositories: If you have multiple checkout steps in your job, your source code is checked out into directories named after the repositories as a subfolder of s in (Agent.BuildDirectory). If (Agent.BuildDirectory) is C:\agent\_work\1 and your repositories are named tools and code, your code is checked out to C:\agent\_work\1\s\tools and C:\agent\_work\1\s\code.
So if you have script in scripts folder in templates repo you will find it in $(Agent.BuildDirectory)\templates\scripts\script.py.
So then you can use it like this:
- task: PythonScript#0
displayName: 'Run a Python script'
inputs:
scriptSource: 'filePath'
scriptPath: '$(Agent.BuildDirectory)\templates\scripts\script.py'
arguments: '${{ parameters.my_param }}'
