Answer 1

The most flexible way is to combine warnings.filterwarnings() with the warnings.catch_warnings() context manager. This way you ge the flexibility of filterwarnings but the filtering is only applied inside the with block:

import warnings
from Crypto.pct_warnings import RandomPool_DeprecationWarning

with warnings.catch_warnings():
    warnings.filterwarnings(
        action='ignore',
        category=RandomPool_DeprecationWarning,
        message='This application uses RandomPool, which is BROKEN in older releases')
   
    # Do stuff that causes the warning
