I used alias and it works for me. (AMI2 AWS)

alias python=python3

Add this command in .bashrc file and then reboot the server

python --version

It will show python version 3

Because AL2 is picky, unfortunately NONE of these answers is exactly correct. Here's what worked for me just now (as root)-

alternatives --install /usr/bin/python python /usr/bin/python2.7 1
alternatives --install /usr/bin/python python /usr/bin/python3.7 2

3.7 SHOULD be the default now, and you can test with python --version.

To change the default at any time:

update-alternatives --config python

The menu system will prompt you through the change.

To change Python Version 3.x

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.x 1

*** Because sometimes priority is required use, you just add '1' at end of command line.**

To check update

 sudo update-alternatives --list | grep python

Reset Python old version'

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1

Just close terminal and restart.

Python -V
3.x

Good luck

By default, the awscli-bundle install script runs under the system default version of Python. To answer your question you will need to know the path of Python version to use. Then run:

$ sudo /path/to/python/version awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

In my case I would run:

$ sudo /usr/local/bin/python3.7 awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

do above: alias python=python36 in ~.bashrc file (Use emacs, vim, your favorite editor - emacs ~.bashrc) then save file.

then in command line terminal type: source ~/.bashrc (for changes to take effect)

alternatives --set python /usr/bin/python3.5

and then back if you want to

alternatives --set python /usr/bin/python2.7

If you want to see what it currently points to

alternatives --display python

This is a system-wide setting not just for the current user. The system settings are stored in /etc/alternatives

A simple safe way would be to use an alias. Place this into ~/.bashrc or ~/.bash_aliases file:

alias python=python3

Example
$ python --version
Python 2.7.6
$ python3 --version
Python 3.4.3
$ alias python=python3
$ python --version
Python 3.4.3
