Installing python3.6 on ubuntu16.04

Question

I am trying to install python3.6 on ubuntu16.04 LTS but having some issues. I tried adding deadsnakes/ppa and installing it but no success. It is probably because there is no python3.6 for xenial installation anymore?

root@c2d64b30b259:~# apt-add-repository ppa:deadsnakes/ppa
root@c2d64b30b259:~# apt update
root@c2d64b30b259:~# apt install python3.6

E: Unable to locate package python3.6
E: Couldn't find any package by glob 'python3.6'
E: Couldn't find any package by regex 'python3.6'

I also tried building the source. The following commands run fine.

root@c2d64b30b259:~/Python-3.6.0# ./configure
root@c2d64b30b259:~/Python-3.6.0# make
root@c2d64b30b259:~/Python-3.6.0# make install 

However, when running some python scripts which import modules, I get hit with the following errors.

  import pandas as pd
  File "/usr/local/lib/python3.6/site-packages/pandas/__init__.py", line 55, in <module>
    from pandas.core.api import (

Any suggestions would be appreciated. Please note I am running ubuntu16.04 LTS inside a docker environment.

Seems like the issue was with my building the source code that I obtained online. Re-installing with the source from following link seems to resolve my issues.
