Question

Answer 1

这是一种方法:

import warnings
import sys

if not sys.warnoptions:
    warnings.simplefilter("ignore")

def foo(x):

    if x > 100:
        msg = "Warning! x is big!"
        warnings.warn(msg)
    return True

foo(999999)

免责声明

Python documentation建议不要更改此设置:

sys.warnoptions

This is an implementation detail of the warnings framework; do not modify this value. Refer to the warnings module for more information on the warnings framework.
