==Setting Up a New Script==
When you are building a script from scratch, or adding Phidget functionality to an existing script, you'll need to configure your program to properly link the Phidget Python library.


To include the Phidget Python library, add the following line to your code:
Open the command prompt at the location of the example and enter the following command:
 
<syntaxhighlight lang=bash>
<syntaxhighlight lang=python>
python example.py
from Phidget22.PhidgetException import *
from Phidget22.Phidget import *
</syntaxhighlight>
</syntaxhighlight>


Then, you will also have to add a reference to your particular Phidget. For example, you would include the following line for a DigitalInput:
Success! Your program is now running with Phidgets!
 
<syntaxhighlight lang=python>
from Phidget22.Devices.DigitalInput import *
</syntaxhighlight>
 
You can now compile the file as shown in the previous section.
 


The project now has access to Phidgets.

Language - Python

macOS with Terminal

Welcome to using Phidgets with Python! By using Python, you will have access to the complete Phidget22 API, including events.

The terminal is the default environment to make Python programs in macOS, since it's available immediately after installing Python.

Install Phidget Drivers for macOS

Before getting started with the guides below, ensure you have the following components installed on your machine:

  1. You will need the Phidgets macOS Drivers
  2. You will need a version of Python installed on your machine (both 2.7 and 3.6+ are compatible with Phidgets).


The recommended way to install the Phidget22 Python module is using the PIP package manager.

Python versions 2.7.9+ and 3.4+ include PIP by default.

To install the Phidget22 Python module with PIP, simply open the Terminal and enter the command: 

python pip install Phidget22

To install the Phidget22 Python module without PIP, you will need to download the Phidget22 Python module.

After unpacking the Phidget Python module, open the terminal (Applications -> Utilities -> Terminal). Locate the folder containing the Python module and enter the following command: 

python setup.py install

This will build the module and install the Python module files into your site-packages directory.

Finding Code Samples

To find the code sample to use for your Phidget, navigate to the Code Samples page and select your device from the drop-down menu.

Once you select your device, the code sample generator will give you a working code sample, and a selection of options to customize it to your needs.

Using the Code Samples

To use the code sample from the Code Samples page, you can click the Download Example button to download a Python file with the sample code.

Open the command prompt at the location of the example and enter the following command: 

python example.py

Success! Your program is now running with Phidgets!

What's Next?

Now that you have set up Phidgets to work with your programming environment, we recommend you read our guide on Phidget Programming Basics to learn the fundamentals of programming with Phidgets.Next Arrow.png
