QR code generating using python step by step

Here's an example of how to generate a QR code using Python:

Install the qrcode library using pip:

Copy code

pip install qrcode

Import the qrcode library in your Python script:

Copy code

import qrcode

Create a QR code object, specifying the data you want to encode:

Copy code

qr = qrcode.QRCode(version=1, box_size=10, border=5)

qr.add_data("Hello World!")

qr.make(fit=True)

Generate the QR code image:

Copy code

img = qr.make_image(fill_color="black", back_color="white")

Save the QR code image to a file:

Copy code

img.save("qr_code.png")

Now you have successfully generated a QR code image "qr_code.png" which contains the data "Hello World!".

You can also use other libraries such as qrtool,qrcodegen and etc. You can also customize the QR code with different colors, size, and logo.

Please check the documentation of the library for more information: https://pypi.org/project/qrcode/
