I didn’t like Python when I was first introduced to it a couple of years ago. Since that time I’ve learned that it is a great quick-n-dirty language that can be used to build an app or what we used to call a “hack”. The extent of its built-in features and the enormous amount of open source code makes it a natural do-it-yourself language.

Install Tool Chain or Installation Scripts

The first step is to install several tools to facilitate installation of Python modules.

sudo apt-get install -y python-pip git
sudo apt-get install -y build-essential python-dev python-smbus
sudo apt-get install -y i2c-tools

I like to use Flask so install the following for a basic environment.

sudo pip install flask 
sudo pip install requests 
sudo pip install flask-httpauth

My do-it-yourself home automation system uses MQTT for messaging. My Python apps subscribe and publish using the Paho implementation.

sudo pip install paho-mqtt

I like to use Adafruit’s I2C backpack for LED and OLED devices. Their libraries usually require the Python imaging module.

sudo apt-get -y install python-imaging python-pil
