Create Your Own Custom QR Codes with Python’s MyQR in Minutes

In modern life we constantly see QR codes on buses, payment apps, and more, but how are they created? This guide shows you how to generate your own QR codes with Python.

Project Goal

Create a personalized QR code using a program.

Preparation

Editor: Sublime Text 3 Browser: 360 Browser Module: MyQR

Implementation Steps

1. Analyze Online QR Generators

An example of a popular online QR generator (CaoLiao QR) is shown below.

2. Use the MyQR Module

Install the module via pip:

pip install myqr

3. Basic Usage

Running MyQR generates a QR image, which can be scanned to reveal the embedded text.

4. Inspect Help Output

The help screen shows that MyQR can be used as a script or command line tool.

5. Important Parameters

words: content text<br/>version: size (also version)<br/>level: error correction level<br/>picture: background image<br/>colorized: apply color<br/>contrast: contrast level<br/>brightness: brightness level<br/>save_name: output file name<br/>save_dir: output directory

6. Generate a Simple QR Code

Running a basic command creates a QR code that scans to “hello”.

7. QR Code with Background Image

Adding a background image makes the QR code more visually appealing.

8. Colorized QR Code

Setting colorized=True adds color to the QR code.

9. Adjust QR Code Size

Changing the version parameter controls the size of the QR code.

10. Generate Animated QR Code

By setting the picture to a GIF, MyQR can produce a dynamic QR code.

from MyQR import myqr
myqr.run(words='hello', version=10, picture='12.gif', colorized=True, save_name='hello.gif', save_dir='./Game2')

Conclusion

MyQR can also be used via the command line, but Python scripts provide a convenient way to create static and animated QR codes with custom content, colors, and backgrounds.
