有选择地抑制输出python

Question

如何有选择地输出某些python函数而不输出其他函数？

代码：

#!/usr/bin/env python

import os
import sys
import pprint

sys.path.append(os.path.join(os.path.dirname(__file__), '..'))

from m2x.client import M2XClient


KEY = '10e34b827d5e1cd90fds9d011006a7b4'
DEVICE_ID = '161add732eb725402d1182dafd74f907'

client = M2XClient(key=KEY)
device = client.device(DEVICE_ID)

cont = raw_input('Continue? [y/n] ')

if cont == 'y':
    print 'Continued...'
else:
    sys.exit()

输出：

/usr/local/lib/python2.7/dist-packages/requests-2.9.1-    py2.7.egg/requests/packages/urllib3/util/ssl_.py:315: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.
  SNIMissingWarning
/usr/local/lib/python2.7/dist-packages/requests-2.9.1-py2.7.egg/requests/packages/urllib3/util/ssl_.py:120: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning
Continue? [y/n]

对用户的期望输出：

Continue? [y/n]

如果生成警告的是urllib3库，最好的地方是它的文档：

http://urllib3.readthedocs.org/en/latest/security.html#disabling-warnings

所以：

import urllib3
urllib3.disable_warnings()

也就是说，抑制关于HTTPS安全性的警告可能是一个非常糟糕的主意。：-）
