I think when you install python it puts export path statements into your ~/.bash_profile file. So if you do not intend to use Python 2 anymore you can just remove that statement from there. Alias as stated above is also a great way to do it.

Here is how to remove the reference from ~/.bash_profile - vim ./.bash_profile - remove the reference (AKA something like: export PATH="/Users/bla/anaconda:$PATH") - save and exit - source ./.bash_profile to save the changes
