Everytime I open up a terminal, I get the below message printed on the shell screen.

bash: /usr/lib/command-not-found: /usr/bin/python3: bad interpreter: Too many levels of symbolic links

Could someone help me understand what is happening here and how I could fix this issue?

EDIT: 

ls -l /usr/bin | grep python3

returned the below 

lrwxrwxrwx 1 root   root           29 Aug 15 20:59 dh_python3 -> ../share/dh-python/dh_python3

You have cycle with symlinks:

lrwxrwxrwx 1 root   root           18 Oct 24 17:25 python3 -> /usr/bin/python3.5
lrwxrwxrwx 1 root   root           16 Oct 24 17:24 python3.5 -> /usr/bin/python3

But I have no idea how you get it and don't know what to suggest to resolve it :)

May be reinstall will help you. Or may be if you tell us what system you use and how you install python (commands and sequence of this command you use and/or which manual you use to install/upgrade python), it will help to understand what is going on and how to fix it.

You can try which python to see the path of python that you are currently on and then create a link from /usr/bin/python3 link to your current python path as:

sudo ln -s <your-current-python-path> /usr/bin/python3

to see the sym links you can use ls -l /usr/bin/python3 that will show existing links and you can remove that using rm -i /usr/bin/python3
