In this article, we are going to write a short script to generate barcodes using Python. We’ll be using the python-barcode module which is a fork of the pyBarcode module. This module provides us the functionality to generate barcodes in SVG format. Pillow is required to generate barcodes in image formats (such as png or jpg).
Modules Needed
- python-barcode: This module is used to create bar codes as SVG objects. It provides us the power to create different standard types of barcodes such as EAN-8, EAN-13, EAN-14, UPC-A, JAN, ISBN-10, ISBN-13, and many more. To install this module type the below command in the terminal.
pip install python-barcode
- Pillow: This is used to create the barcodes in the image format. To install this module type the below command in the terminal.
pip install pillow
Here, we are going to generate a barcode in the EAN-13 format. First, let’s generate it as an SVG file.
Python3
# import EAN13 from barcode modulefrom barcode import EAN13 # Make sure to pass the number as stringnumber = '5901234123457' # Now, let's create an object of EAN13# class and pass the numbermy_code = EAN13(number) # Our barcode is ready. Let's save it.my_code.save("new_code") |
Output:
Generated barcode as SVG file
Now, let’s generate the same barcode in PNG format.
Python3
# import EAN13 from barcode modulefrom barcode import EAN13 # import ImageWriter to generate an image filefrom barcode.writer import ImageWriter # Make sure to pass the number as stringnumber = '5901234123457' # Now, let's create an object of EAN13 class and # pass the number with the ImageWriter() as the # writermy_code = EAN13(number, writer=ImageWriter()) # Our barcode is ready. Let's save it.my_code.save("new_code1") |
Output:
Generated barcode as PNG file
