+## Description: 
+- Let's [**look**](https://github.com/Iamtripathisatyam/Awesome_Python_Scripts/blob/main/GUIScripts/QR%20Code%20Scanner/qr_code_scan.py) at a Python script that scans a picture and outputs the results.
+- This project will read **QR** codes and show the information contained within them.
+- It will first accept an image as input, then use **pzbar** to convert it to text, and then show the result.
+
+## Procedure to follow: 
+- pip install **pyzbar**
+- pip install **pywebio**
+- pip install **Pillow**
+- Change to the directory where the image will be scanned.
+- Take the user's input and verify whether or not the input file name exists.
+- Open the image and use **decode** to decode it.
+- Finally, use **UTF-8** to decode the text and show it on the output screen.
+
+Sample Output:
