From restaurant e-menus to airline boarding passes, QR codes<\/strong> have numerous applications that impact your day-to-day life and enrich the user\u2019s experience. Wouldn\u2019t it be great to make them look good, too? With the help of this tutorial, you\u2019ll learn how to use Python to generate beautiful QR codes for your personal use case. <\/p>\n In its most basic format, a QR code contains black squares and dots on a white background, with information that any smartphone or device with a dedicated QR scanner can decode. Unlike a traditional bar code, which holds informationation horizontally, a QR code holds the data in two dimensions, and it can hold over a hundred times more information.<\/p>\n In this tutorial, you\u2019ll learn how to:<\/strong><\/p>\n Traditionally, QR codes have been predominantly black-and-white. Now, thanks to creative innovations, QR codes come in all sorts of shapes, sizes, and colors. If you\u2019d like to learn how to create not only two-tone QR codes but also colorful and artistic ones, then this is the tutorial for you.<\/p>\n Free Bonus:<\/strong> Click here to download the sample code<\/a> that shows you how to generate a beautiful code with Python.<\/p>\n<\/div>\n To begin with, you\u2019re going to create a black-and-white QR code that encodes some content. To follow along with this tutorial, you\u2019ll need to install Segno<\/a>, which is a popular Python library for generating QR codes. To install Segno, you can run Once you\u2019ve installed Note:<\/strong> You can also use the QR codes are capable of handling all types of data, such as alphanumeric characters, symbols, and even URLs. To begin your journey of generating QR codes in Python, you\u2019ll start by creating a QR code object that will encode the text At this stage, you\u2019ve written the code to encode the text Now, to generate a black-and-white QR code that you can actually view and scan, you\u2019ll need to store the encoded content as a variable and use the The If you\u2019d like to save the image in a different directory, then you can specify the desired file path<\/a> together with the filename as an argument in the Once you\u2019ve finished writing the steps for generating a black-and-white QR code in Congratulations, you\u2019ve just created a black-and-white QR code that encodes the text You may have found that the QR code image is a little difficult to view or read because of its size, so the next item that you\u2019re going to adjust is the size of your basic QR code.<\/p>\n When trying to scan your QR code image or the QR code in the tutorial, you might have found it difficult to read because of its size.<\/p>\n<\/div>\n [ Improve Your Python With ?

Using Python to Generate a Basic QR Code<\/a><\/h2>\n
pip<\/code><\/a> from your command line<\/a>: <\/p>\n<\/span>$ <\/span>python <\/span>-m <\/span>pip <\/span>install <\/span>segno\n<\/code><\/pre>\n<\/div>\nsegno<\/code>, create a Python file named basic_qrcode.py<\/code>. To create a black-and-white QR code object that encodes some content, you\u2019ll have to use the make_qr()<\/code> function. This ensures that you\u2019re creating a full-size QR code, and the only mandatory argument you\u2019ll need to pass is the information that you want to encode. <\/p>\nmake()<\/code><\/a> function to create a QR code object, but depending on the content you\u2019re encoding, it might create a micro QR code. For the sake of this tutorial, you can think of that as a smaller QR code. To enforce the creation of a full-size QR code, you should use the make_qr()<\/code> function.<\/p>\n<\/div>\n\"Hello, World\"<\/code>:<\/p>\n<\/span># basic_qrcode.py<\/span>\n\nimport<\/span> segno<\/span>\n\nsegno<\/span>.<\/span>make_qr<\/span>(<\/span>\"Hello, World\"<\/span>)<\/span>\n<\/code><\/pre>\n<\/div>\n\"Hello, World\"<\/code> by passing this to the make_qr()<\/code> function. This will greet your user with that text, and it might also offer the option of searching for \"Hello, World\"<\/code> on the Internet.<\/p>\n.save()<\/code><\/a> method to save your QR code as an image. Here\u2019s an example of how you can create a variable<\/a> called qrcode<\/code> that encodes the text \"Hello, World\"<\/code> as a black-and-white QR code object, which you then save as a PNG file called basic_qrcode.png<\/code>: <\/p>\n<\/span># basic_qrcode.py<\/span>\n\nimport<\/span> segno<\/span>\n\nqrcode<\/span> =<\/span> segno<\/span>.<\/span>make_qr<\/span>(<\/span>\"Hello, World\"<\/span>)<\/span>\nqrcode<\/span>.<\/span>save<\/span>(<\/span>\"basic_qrcode.png\"<\/span>)<\/span>\n<\/span><\/code><\/pre>\n<\/div>\n.save()<\/code> method serializes the QR code into a file format of your choice, as long as the chosen format is supported. When you apply .save()<\/code> to the variable that you\u2019ve created with the encoded content, you need to specify the filename including an optional file path. In the example above, you\u2019re saving the QR code image as a file named basic_qrcode.png<\/code> in the same directory where you\u2019ll be executing your code, so you don\u2019t specify a file path. <\/p>\n.save()<\/code> method.<\/p>\nbasic_qrcode.py<\/code>, you\u2019ll need to run the Python script<\/a> from your command line:<\/p>\n<\/span>$ <\/span>python <\/span>basic_qrcode.py\n<\/code><\/pre>\n<\/div>\n\"Hello, World\"<\/code> using make_qr()<\/code> and .save()<\/code>. You can now scan your QR code image, which you\u2019ll find in the same directory that you\u2019re running your code from. Or, you can scan the QR code image below:<\/p>\n![\"An](\"https:\/\/files.realpython.com\/media\/my_first_qrcode.b078ef62bf2b.png\")
