背景

脚本中使用了paramiko，在高版本的3.9Python环境下很丝滑。
给到指定环境因为Python版本不同（3.6），有Warning信息很碍事。

报警信息

/usr/local/lib/python3.6/site-packages/paramiko/transport.py:33: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography and will be removed in a future release.
  from cryptography.hazmat.backends import default_backend

解决

import warnings

在导入前

import warnings
warnings.filterwarnings( action = 'ignore' , module = '.*paramiko.*' )
import paramiko

在导入后（试了没用）

import warnings
from cryptography.utils import CryptographyDeprecationWarning
warnings.filterwarnings( "ignore" , category = CryptographyDeprecationWarning )
