    python2 --version
    python3 --version

    Verify your result looks like this:

    Python 2.7.14

    Python 3.6.5

    If python isn’t installed, run the following commands to install Python 2.7 and Python 3.6

    sudo yum -y update

    sudo yum install -y python27

    sudo yum install -y python36

Part 4 – How to Create a Python Runtime?

In this part, you will create a python runtime and configure it to use Python 3.6

2. Ensure virtualenv is installed

virtualenv --version

3. Remove the alias configured with python command

unalias python

4. Obtain Python 3.6 location

which python36

5. Switch to the environments directory

cd ~/environment/

6. Create a new virtual environment and configure it to use Python 3.6

virtualenv -p /usr/bin/python36 vpy36

7. In the virtual environment, switch to Python 3.6

source vpy36/bin/activate

8. Verify Python in the virtual environment is configured to use version 3.6

python --version

9. Deactivate the virtual environment


10. Re-create alias for Python

alias python=/usr/bin/python27

Part 5 – How to Create a Simple Python Program and Run it?

In this part, you will create a simple Python program and run it

2. In the editor, enter the following code

import sys print('Hello, World!') print('The sum of 2 and 3 is 5.') sum = int(sys.argv) + int(sys.argv) print('The sum of {0} and {1} is {2}.'.format(sys.argv, sys.argv, sum))

3. Save the file by click File > Save on the menu bar.

4. In the Save As dialog box, enter test.py as the file name and click Save button

5. Switch to the Terminal window. (If you don’t have terminal window open, click Window > New Terminal on the menu bar)

6. Run the following command to execute test.py

python test.py 5 6

Notice it shows the output like this:

Part 6 – How to Execute the Python Program using Run Configuration?

In this part, you will execute the test.py program using Run Configuration

1. On the menu bar, click Run > Run Configurations > New Run Configuration

2. In the Idle tab, click Runner: Auto and select Python 3

3. In the file explore, double click test.py to open the file in a tab

Verify the result shows up like this:

Part 7 – Clean Up

In this part, you will close the tabs

1. In Cloud9 IDE, close all tabs
