How to Create a QR Code using Python

A QR code (short for Quick Response code) is a type of two-dimensional barcode that can be read by smartphones and other mobile devices. It consists of a black and white square grid that can store a variety of information, including text, URLs, contact information, and even payment information.

In this tutorial , we will present you with a tutorial on how to create a QR code using Python. To create QR codes using the Python programming language, follow these steps

• Step 1: Install the qrcode library
• Step 2: Import the qrcode library
• Step 3: Create a QR Code Object
• Step 4: Set the URL
• Step 5: Generate the QR Code
• Step 6: Add an Image File Extension
• Step 7: Save the Image

Step 1: Install the qrcode library

The qrcode library is a python library for generating QR codes. To install it, run the following command in your terminal:

pip install qrcode

Step 2: Import the qrcode library

Once installed, you can import the qrcode library in your python project by adding the following code:

import qrcode

Step 3: Create a QR Code Object

Next, you need to create a QR Code object. You can do this by initializing a QRCode instance with the version, box size, and border you want for the QR code. For example:

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

Step 4: Set the URL

Next, you need to collect the URL you are going to be using for the QR code and set it. To do so we add:

data = input("Enter the url you want as a QR code: ")
qr.add_data(data)

Step 5: Generate the QR Code

Now that you’ve created the QR Code object, you need to generate the actual QR code image. To do this, you need to add the following code:

qr.make(fit=True)

This will generate the QR code image based on the data contained in the QR Code object you created in Step 3.

Step 6: Add an Image File Extension

Now that you have generated the QR code image, you need to add an image file extension to it. You can do this by adding the following code:

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

This will create an image object with a black foreground and white background, which is suitable for printing or displaying on a screen.

Step 7: Save the Image

To save the image to your computer, you need to add the following code:

img.save("qrcode.png")

This will save the image file as “qrcode.png” in your current working directory. That’s it! You’ve successfully created your QR code.
