# RuntimeError: cannot reuse already awaited coroutine

- **ID:** `python/asyncio-cannot-run-coroutine-already-running`
- **Domain:** python
- **Category:** runtime_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

A coroutine object was awaited more than once. Coroutines in Python are single-shot; reusing the same coroutine object (e.g., in a retry loop or cached in a variable) raises this error.

## Workarounds

1. **** (95% success)
   ```
   async def fetch(): ...
for _ in range(3):
    await fetch()   # new coroutine each iteration
   ```
2. **** (85% success)
   ```
   task = asyncio.ensure_future(fetch())
await task
await task   # Tasks can be awaited multiple times
   ```
3. **** (88% success)
   ```
   from functools import partial
make = partial(fetch, url)
await make()
await make()
   ```

## Dead Ends

- **** — The coroutine frame is exhausted; send raises StopIteration immediately. (95% fail)
- **** — Shallow copy shares the same frame; awaiting the copy raises the same error. (90% fail)
