RuntimeWarning：啟用tracemalloc以獲取對象分配回溯

Question

我讀了Jupiter教程索引

並嘗試過

In [15]: print('before sleep'); sleep(12); print('after sleep')
before sleep
/home/me/anaconda3/bin/ipython:1: RuntimeWarning: coroutine 'sleep' was never awaited
  #!/home/me/anaconda3/bin/python
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
after sleep

對警告很困惑，

Answer 1

此錯誤意味着函數（實際上是協程）“睡眠”從未執行過。

嘗試將其替換為：

asyncio.get_event_loop().run_until_complete(sleep(25))

否則，只需使用非異步睡眠方法：

import time
time.sleep(25)

祝好運！
