How to get browser console error messages using Selenium WebDriver + python

Console error png We have been trying to print the console errors for the particular site by using the following code. But we are unable to catch console errors. Can anyone give quick response But we are getting

Line of Code :

driver.get_log('browser')

Error :

[{u'source': u'deprecation', u'message': u"https://xxxxx/static/vendor/vendor.bundle.js?v=16 902 Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.", u'timestamp': 1515593047810, u'level': u'WARNING'}]

Line of Code :

driver.get_log('driver')

Error : 

[{u'timestamp': 1515593061561, u'message': u'Unable to evaluate script: disconnected: not connected to DevTools\n', u'level': u'WARNING'}, {u'timestamp': 1515593071847, u'message': u'Unable to evaluate script: disconnected: not connected to DevTools\n', u'level': u'WARNING'}]

Code Block :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

capabilities = DesiredCapabilities.CHROME
capabilities['loggingPrefs'] = { 'browser':'ALL' }

this Error: looks like a JS error being printed:

[{u'source': u'deprecation', u'message': 
 u"https://xxxxx/static/vendor/vendor.bundle.js?v=16 902 Synchronous 
 XMLHttpRequest on the main thread is deprecated because of its detrimental 
 effects to the end user's experience. For more help, check 
 https://xhr.spec.whatwg.org/.", u'timestamp': 1515593047810, u'level': 
 u'WARNING'}]

I believe what that is outputing is what you are looking for.

Example from console on https://stackoverflow.com/: enter image description here

and this is my output from for log in driver.get_log('browser'): print(log):

{'level': 'SEVERE', 'message': 'https://secure.quantserve.com/quant.js -
