for x in pnq.query([1, 2, 3]).map(lambda x: x * 2):
print(x)
# => 2, 4, 6
pnq.query([1, 2, 3]).map(lambda x: x * 2).result()
# => [2, 4, 6]
pnq.query([1, 2, 3]).filter(lambda x: x == 3).one()
# => 2
import asyncio
import pnq
async def aiter():
yield 1
yield 2

# => 2, 4, 6
await pnq.query(aiter()).map(lambda x: x * 2)
# => [2, 4, 6]
await pnq.query(aiter()).filter(lambda x: x == 3)._.one()
