Note: I cannot reproduce your exact problem (tested with several options on a centos:7 docker container with python2). Meanwhile, below, a procedure to install in python3 that I use and I know is working.

Python 2 is dead. Although it still sits arround on a centos:7 installation, you should definitely install ansible with python 3.

First make sure you have python3 and pip3:

yum install -y python3-pip

In case you still have pip2 installed (which seems to be the case), make sure the pip command defaults to the python3 version

pip3 install --upgrade --force-reinstall pip

Now you can install ansible without any obsolescence warnings and a version of python that will be supported

pip install ansible
