When it execute websocket/test.py file which getting repeated text :

```

}
```

i want to remove that blank and repeated text is it possible to only print result array

Code:

```
async def run_test(uri):
async with websockets.connect(uri) as websocket:

wf = wave.open(sys.argv[1], "rb")
await websocket.send('{ "config" : { "sample_rate" : %d } }' % (wf.getframerate()))
buffer_size = int(wf.getframerate() * 0.2) # 0.2 seconds of audio
while True:
data = wf.readframes(buffer_size)

if len(data) == 0:
break

await websocket.send(data)
print (await websocket.recv())

await websocket.send('{"eof" : 1}')
print (await websocket.recv())

asyncio.get_event_loop().run_until_complete(
run_test('ws://localhost:2700'))

```
