【Python】パーフェクトPythonの12章・asyncio項目でエラーが警告への対処法

Last updated at Posted at 2022-03-11

パーフェクトPythonの12章・asyncioの項目でエラーが警告が発生

基本情報

環境 : Python3.10
PC : MacBook Pro
Editor : Visual Studio Code

警告内容

DeprecationWarning: There is no current event loop
  loop = asyncio.get_event_loop()

Python3.10では、get_event_loop()を呼ぶと警告を発生する模様。
get_event_loop()ではなく、get_running_loopが推奨されている。

【参照】

パーフェクトPythonは、Python Version3.8ベースで書かれているので、少しばかり相違点があり、意外なエラーが出るので、注意が必要ですね。
