Create Custom QR Codes in Python with MyQR – A Step‑by‑Step Guide

1. Install MyQR library

Open the command prompt (Windows+R, then type cmd) and run: pip install myqr Wait until the installation completes successfully.

2. Import MyQR in PyCharm

In PyCharm go to File → Settings → Python Interpreter , click the + button, search for MyQR, select the first result and click Install Package . After installation you can import the library in your code:

from MyQR import myqr

3. Generate a plain QR code

Use the following code to create a simple QR code that encodes a URL or text: myqr.run(words='https://baidu.com') The generated file qrcode.png will appear in the same directory as your script.

4. Generate a QR code with a custom picture

Add the picture argument to embed an image into the QR code:

myqr.run(
    words='https://baidu.com',
    picture='C:\Users\jinyj\Desktop\p1.png'
)

5. Generate a colored QR code

Set colorized=True to produce a colored QR code (requires a custom picture as well):

myqr.run(
    words='https://baidu.com',
    picture='C:\Users\jinyj\Desktop\p1.png',
    colorized=True
)

6. Extended parameters

MyQR offers many additional options for fine‑tuning the output. Below is a comprehensive example:

myqr.run(
    words='https://example.com',
    version=5,               # error correction level
    level='H',                # L, M, Q, H (increasing redundancy)
    picture='logo.png',       # path to an image (can be GIF)
    colorized=True,           # True for color, False for black‑white
    contrast=1.0,             # image contrast
    brightness=1.0,          # image brightness
    save_name='custom_qr.png',
    save_dir=r'C:\Users'
)

These parameters let you control the QR code size, error correction, embedded image, colorization, contrast, brightness, and output location.
