Pydantic is a popular library which we can use for defining our custom objects and making it so much easy to use for day to day coding.  Here is one of the example that i link can really boost productivity - this is how we can assign data into our objects. from pydantic import BaseModel , EmailStr , Field class UserRegistration ( BaseModel ):     username : str = Field ( min_length = 3 , max_length = 20 )     age : int = Field ( ge = 18 )   # Must be 18 or older # Incoming untrusted JSON data raw_input = { "username" : "alice_dev" , "email" : "alice@example.com" , "age" : "25" } # Pydantic validates and coerces data types automatically user = UserRegistration ( ** raw_input ) print ( user . age )   # Output: 25 (converted from string to int) Application settings To work with an app config that automatically read from DATABASE_URL and REDIS_URL environment variables. Pre-req, you need to install  uv add pydantic_set...

orjson is a json library that is fast and getting popular.  Here are example code to work with same data  import orjson from dataclasses import dataclass from datetime import datetime @ dataclass class User :     id : int     name : str     created_at : datetime user = User ( id = 1 , name = "Alice" , created_at = datetime . now ()) # --- SERIALIZATION (Python Object -> JSON bytes) --- json_bytes = orjson . dumps ( user ) print ( json_bytes ) # Output: b'{"id":1,"name":"Alice","created_at":"2026-10-04T15:12:00+00:00"}' # --- DESERIALIZATION (JSON bytes/str -> Python Dict) --- data = orjson . loads ( json_bytes ) print ( data ) # Output: {'id': 1, 'name': 'Alice', 'created_at': '2026-10-04T15:12:00+00:00'} print(data['id']) # output 1

When using async library, it is always good to use TaskGroup to manage execution of different tasks where we use create_task to create async task.  import asyncio import time async def worker ( task_id : int , delay : int ):     print ( f "Task { task_id } started (sleeping { delay } s)..." )     await asyncio . sleep ( delay )     print ( f "Task { task_id } finished after { delay } s!" )     return f "Result { task_id } " async def main ():     start_time = time . time ()         # TaskGroup manages execution and waits until all tasks finish     async with asyncio . TaskGroup () as tg :         t1 = tg . create_task ( worker ( 1 , 1 ))         t2 = tg . create_task ( worker ( 2 , 2 ))         t3 = tg . create_task ( worker ( 3 , 10 ))         # All tasks are guaranteed complete after exiting the contex...

I was trying to deploy using this command and pretty sure agentic platform is available here in Australia South East 2 (Melbourne) and I wasn't try to deploy to Sydney.  uv run adk deploy agent_engine agent_togo --project="project-015f2405-16e7-4b36-996" --region="australia-southeast2" Bump into this error when trying to deploy my adk sample app to google agentic platform.  To be fair, I didn't have my gcloud cli setup on my laptop. So I fixed that with  gcloud auth application-default login Deploy failed: ('invalid_grant: Bad Request', {'error': 'invalid_grant', 'error_description': 'Bad Request'}) Then bump into this error which is a generic error. And that drove me to check Log Explorer to find out more details Deploy failed: Failed to create Agent Engine: {'code': 10, 'message': 'Please refer to our troubleshooting pages (e.g., https://docs.cloud.google.com/gemini-enterprise-agent-platform/troub...

This is my main.py which uses the  Qwen3.8-2B-Distill-GGUF model. And the instruction is pretty much the same as previous model how ever, it does not seems to 'want' to read from start until end.  And because of that, the results is not so accurate.  """Have the model READ a README, detect its runtime, and extract the commands. Then start a matching container, run each command in it, and stop it.
