Barcode generating using python step by step

Barcode generating using python step by step 

Here is a step-by-step guide on how to generate a barcode using Python:

Install the python library for generating barcode using pip: pip install barcode.

Create a new Python script and import the barcode library by adding the following line at the top of your script: import barcode

Create an instance of the barcode type you want to generate. For example, if you want to generate a Code128 barcode, you can use the following code:

Copy code

from barcode import Code128

barcode = Code128("123456789")

Create the barcode image using the save() method. You will need to specify the file path and the file type as an argument. Here's an example of how to do this:

Copy code

barcode.save("barcode")

You can also create the barcode image in memory using the render() method.

Copy code

from io import BytesIO

stream = BytesIO()

barcode.render(stream)

Finally, you can display the barcode using any library such as matplotlib.

Copy code

import matplotlib.pyplot as plt

from PIL import Image

with open("barcode.png", "rb") as image_file:

    img = Image.open(image_file)

    plt.imshow(img)

    plt.show()

The above code snippet is just an example, you can use different libraries to generate barcodes and also you can generate barcodes in different formats such as png, svg, jpeg etc.
