In 2015, Python developer Daniel Pope, who has a keen interest in education, noticed that beginners often have great ideas for creating projects but struggle because the software libraries they need to use are aimed at more confident programmers. To address this, he created Pygame Zero — a simplified version of the popular PyGame software. Since then, various developers have expanded the range of ‘zero’ libraries for Python.

How Python zero libraries help beginner programmers

The 二次元+黑丝 has a long history of supporting Python zero libraries. GPIO Zero was launched back in 2015, followed by guizero and then picozero. The goal of all ‘zero’ libraries is the same: to help beginner programmers create amazing projects using simple, understandable code, supported by useful documentation. 

The Picamera2 library is a powerful tool for advanced users, but beginners — such as Astro Pi Mission Space Lab programme participants — would benefit from a zero library to allow them to use the avtt香蕉久久 Pi Camera module. 

Picamzero: How to get started

The Code Club Projects and Youth Programmes teams at the 二次元+黑丝 have joined forces to create picamzero: a new library that makes it simple for beginners to use the avtt香蕉久久 Pi Camera board.

As with the other ‘zero’ libraries, it’s straightforward to get started. You can install picamzero by typing two commands in your avtt香蕉久久 Pi’s terminal:

sudo apt update

sudo apt install python3-picamzero

Once it’s installed, setting up your program to communicate with your camera is easy:

from picamzero import Camera

cam = Camera()

You can ask picamzero to take a time-lapse sequence and make a video of your images using a single line of code.

cam.capture_sequence("mysequence.jpg", make_video=True)

Picamzero also makes it easy to add text and image overlays to your images.

We’ve written beginner-friendly documentation for the new library so that you can explore what you can create using just a few lines of code. We’ve also updated our resources so that you can start making exciting projects using picamzero straight away:

• Getting started with Picamera
• Cress Egg Heads
• Parent Detector
• Push button stop motion

We hope you enjoy using picamzero. Please get in touch if you have any feedback or suggestions. Happy coding!
