Let's leave the warnings as they are: they explain what's going on and guide the user to possible solutions. The best solution for them is to upgrade Python.

[x0rw]

when you do 'import urllib3 '
do 'import urllib3'
and then type
'urllib3.disable_warnings()'

@bestofg -- Doesn't seem to have any effect.

$ sudo pip install urllib3 --upgrade

Then:

     ... 

... still gives the warnings:
