Here are the steps I used to manually install python3 for anyone else who wants to do it as it s not super straight forward  EDIT  It s almost certainly easier to use the yum package manager  see other answers     Note  you ll probably want to do sudo yum groupinstall  Development Tools  before doing this otherwise pip won t install   wget https   www python org ftp python 3 4 2 Python-3 4 2 tgz tar zxvf Python-3 4 2 tgz cd Python-3 4 2 sudo yum install gcc   configure --prefix  opt python3 make sudo yum install openssl-devel sudo make install sudo ln -s  opt python3 bin python3  usr bin python3 python3  should start the interpreter if it s worked  quit   to exit

As   NickT said   there s no python3 4-6  in the default yum repos in Amazon Linux 2  as of today it uses 3 7 and looking at all answers here we can say it will be changed over time   I was looking for python3 6 on Amazon Linux 2 but amazon-linux-extras shows a lot of options but no python at all  in fact  you can try to find the version you know in epel repo   sudo amazon-linux-extras install epel  yum search python   grep   python3  x8   python34 x86 64   Version 3 of the Python programming language aka Python 3000 python36 x86 64   Interpreter of the Python programming language

Note  This may be obsolete for current versions of Amazon Linux 2 since late 2018  see comments   you can now directly install it via yum install python3    In Amazon Linux 2  there isn t a python3 4-6  in the default yum repos  instead there s the Amazon Extras Library    sudo amazon-linux-extras install python3   If you want to set up isolated virtual environments with it  using yum install d virtualenv tools don t seem to reliably work     virtualenv --python python3 my venv     Calling the venv module tool is less finicky  and you could double check it s what you want expect with python3 --version beforehand   python3 -m venv my venv     Other things it can install  versions as of 18 Jan 18     ec2-user x     amazon-linux-extras list   0  ansible2   disabled     2 4 2     1  emacs   disabled     25 3     2  memcached1 5   disabled     1 5 1     3  nginx1 12   disabled     1 12 2     4  postgresql9 6   disabled     9 6 6     5  python3 latest  enabled     3 6 2     6  redis4 0   disabled     4 0 5     7  R3 4   disabled     3 4 3     8  rust1   disabled     1 22 1     9  vim   disabled     8 0    10  golang1 9   disabled     1 9 2    11  ruby2 4   disabled     2 4 2    12  nano   disabled     2 9 1    13  php7 2   disabled     7 2 0    14  lamp-mariadb10 2-php7 2   disabled     10 2 10 7 2 0

If you do a  sudo yum list   grep python3   you will see that while they don t have a  python3  package  they do have a  python34  package  or a more recent release  such as  python36   Installing it is as easy as    sudo yum install python34 python34-pip

Adding to all the answers already available for this question  I would like to add the steps I followed to install Python3 on AWS EC2 instance running CentOS 7  You can find the entire details at this link    https   aws-labs com install-python-3-centos-7-2   First  we need to enable SCL  SCL is a community project that allows you to build  install  and use multiple versions of software on the same system  without affecting system default packages   sudo yum install centos-release-scl   Now that we have SCL repository  we can install the python3  sudo yum install rh-python36   To access Python 3 6 you need to launch a new shell instance using the Software Collection scl tool   scl enable rh-python36 bash   If you check the Python version now you   ll notice that Python 3 6 is the default version  python --version   It is important to point out that Python 3 6 is the default Python version only in this shell session  If you exit the session or open a new session from another terminal Python 2 7 will be the default Python version   Now  Install the python development tools by typing   sudo yum groupinstall    Development Tools      Now create a virtual environment so that the default python packages don t get messed up   mkdir   my new project cd   my new project python -m venv my project venv   To use this virtual environment   source my project venv bin activate   Now  you have your virtual environment set up with python3
