Update:

Is it possible to add or change a command that executes a pipeline on Azure DevOps?

Running my program locally on Visual Studio Code, I do get outputs.

However, running my GitHub origin branch on Azure DevOps does not yield any output.

I followed a Stack Overflow answer, which references this solution to a GitHub Issue.

I have implemented the below, but Azure's Raw Logs return blank on my Python logging.

test_logging.py:

import logging

filename = "my.log"

global logger
logger = logging.getLogger()
logger.setLevel(logging.INFO)
formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
open(filename, "w").close()  # empty logs
fileHandler = logging.FileHandler(filename)
fileHandler.setFormatter(formatter)
fileHandler.setLevel(logging.INFO)
logger.addHandler(fileHandler)

logger.error('TEST')

# fetch logs
with open(filename, "r") as fileHandler:
    logs = [log.rstrip() for log in fileHandler.readlines()]
open(filename, "w").close()  # empty logs
print('logs = ', logs)

>>> logs = []

host.json:

{
  "version":  "2.0",
  "logging": {
    "fileLoggingMode": "always",
    "logLevel": {
      "default": "Debug"
    }
  } 
}

I then tried this alternative host.json from post:

"logging": {
    "fileLoggingMode": "debugOnly",
    "logLevel": {
        "default": "None",
        "Host.Results": "Information",
        "Function": "Information",
        "Host.Aggregator": "Information"
    },
    "applicationInsights": {
        "samplingSettings": {
            "isEnabled": false,
            "maxTelemetryItemsPerSecond": 5
        }
    }
}
