Are there execution sequences when using asynchronous operations?

Yes, when using asynchronous operations, there is a sequence of execution, but it may differ from sequential code.

In Python with async/await:

• Code inside a single async function executes sequentially until the first await.
• When await is encountered, control is passed to another coroutine, allowing other tasks to run.
• After await completes, execution resumes at the next line of the current function.

Thus, the sequence within one coroutine is preserved, but the order between different coroutines can be unpredictable, as they run concurrently.

Example:

import asyncio

async def task(name):
    print(f"Start {name}")
    await asyncio.sleep(1)
    print(f"End {name}")

async def main():
    await asyncio.gather(task("A"), task("B"))

asyncio.run(main())

Here, "Start A" and "Start B" are printed almost simultaneously, then after a second, "End A" and "End B" appear — their order may vary.
