Waiting for validation
What does the variable tg represent in the first_function and within the context of the main function in the code below that uses asyncio.TaskGroup?
import asyncio
async def second_function():
for _ in range(5):
print('Second function iteration')
await asyncio.sleep(1)
async def first_function(tg: asyncio.TaskGroup):
for _ in range(5):
tg.create_task(second_function())
print('First function iteration')
await asyncio.sleep(5)
async def main():
async with asyncio.TaskGroup() as tg:
task1 = tg.create_task(first_function(tg))
await task1
asyncio.run(main())
