Python 3-da asyncpg yordamida PostgreSQL ma'lumotlar bazasiga qanday ulanish mumkin? Ulanish tuzilganidan so'ng, men operatsiyalarni bajarmoqchiman. Bundan tashqari, SELECT so'rovi yordamida barcha mos keladigan satrlarni matrga nusxa ko'chirmoqchiman.

Python 3-da asyncpg yordamida PostgreSQL ma'lumotlar bazasiga ulanish uchun siz avval asyncpg modulini o'rnatishingiz kerak: ``bash pip install asyncpg `` ` Keyin ma'lumotlar bazasiga ulanishingiz va operatsiyalarni amalga oshirishingiz mumkin. Mana misol kodi: ``python import asyncio import asyncpg async def main: # ma'lumotlar bazasiga ulanish = conn await asyncpg.connect(user='username', password='password', database='dbname', host='calhost') # async bilan operatsiyalarni amalga oshirish conn.transaction): # SELECT so'rovni bajaring va natijalarni Array = conn await natijalariga ko'chirib qo'ying.<|eot_id|>
