+## Barcode Generator
+### 🎯 Goal
+The goal of this project is to create a barcode generator using Streamlit. The application allows users to generate EAN-13, EAN-8, and UPCA barcodes based on a user-provided numeric code, and provides the ability to download the generated barcode image.
+
+### 🧾 Description
+This project is a barcode generator built with Streamlit, providing an easy-to-use interface for generating barcodes. Users can select from multiple barcode formats (EAN-13, EAN-8, UPCA), input the appropriate numeric code, and generate a barcode image. The generated barcode is displayed and can be downloaded as a PNG file.
+
+### 🧮 What I had done!
+Developed a Streamlit interface for selecting barcode types and entering barcode numbers.
+Validated the input based on the selected barcode format.
+Generated and displayed barcodes using the python-barcode library.
+Added functionality for users to download the generated barcode image.
+### 📚 Libraries Needed
+Streamlit - For building the user interface.
+python-barcode - To generate the barcodes.
+base64 - For encoding the barcode image to display and download in the Streamlit app.
+### 📢 Conclusion
+The barcode generator offers a simple and effective way for users to generate and download barcodes in various formats. The app handles input validation and provides a clean interface for creating barcodes, making it a useful tool for generating barcodes on demand.
