Install the Latest Version of Python

Here's how you install Python 3.6 into your workspace:

cd /home/ubuntu
tar -xvf Python-3.6.2.tar.xz 
cd Python-3.6.2/
sudo make altinstall

You should test to make sure you've got Python 3.6 installed afterwards:

mikematera:~/Python-3.6.2 $ python3.6 --version
Python 3.6.2
mikematera:~/Python-3.6.2 $

Run The Example 50 App

Run these commands. You will notice a popup showing you where you can view your running web application:

cd ~/workspace/ex50
python ./bin/

Go to the link and check it out. You can also use the Preview button.

Change Python Versions

Look what happens when you run the sample app using a newer version of Python:

mikematera:~/workspace/ex50 $ python3.6 bin/                                                                                                              
Traceback (most recent call last):
  File "bin/", line 1, in <module>
    import web
ModuleNotFoundError: No module named 'web'
