Python script that generates a QR code from user-provided text or a URL using the qrcode library:

import qrcode

def generate_qr_code(data, filename):
    # Create a QR code instance
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_L,
        box_size=10,
        border=4,
    )

    # Add the data to the QR code
    qr.add_data(data)
    qr.make(fit=True)

    # Generate the QR code image
    img = qr.make_image(fill_color="black", back_color="white")

    # Save the QR code image to a file
    img.save(filename)
    print(f"QR code saved as '{filename}'")

if __name__ == "__main__":
    print("QR Code Generator")
    data = input("Enter the text or URL to encode: ")
    filename = input("Enter the filename (e.g., qrcode.png): ")

    # Generate the QR code
    generate_qr_code(data, filename)

Here's how the script works: 1. The qrcode library is imported to generate QR codes. 2. The generate_qr_code function takes two arguments: data (the text or URL to encode) and filename (the name of the file to save the QR code image). 3. Inside the function, a QRCode instance is created with some configuration options, such as version, error correction level, box size, and border width. 4. The add_data method is called to add the provided data to the QR code. 5. The make method is called to generate the QR code image. 6. The make_image method is used to create a PIL image object from the QR code, specifying the fill color (black) and background color (white). 7. The save method is called on the image object to save the QR code image to the specified filename. 8. In the if __name__ == "__main__": block, the script prompts the user to enter the text or URL to encode and the filename for the QR code image. 9. The generate_qr_code function is called with the user-provided data and filename. To run the script, save it to a file (e.g., qr_code_generator.py) and execute it using the Python interpreter. You'll be prompted to enter the text or URL to encode and the filename for the QR code image. After providing the necessary input, the script will generate the QR code image and save it to the specified filename. Note that you need to have the qrcode library installed. You can install it using pip:

pip install qrcode

Feel free to modify the script according to your needs, such as adding error handling, customizing the QR code appearance, or integrating it with a graphical user interface (GUI) framework like Tkinter or PyQt.

⌨️ Extract Text from PDFs with Python Need to extract text from PDF files? Python makes it easy with the PyPDF2 library! First, install the necessary module:

pip install PyPDF2

Then, use this script:

import PyPDF2

# https://t.me/pythonfreebootcamp

pdf_file = 'sample.pdf'
with open(pdf_file, 'rb') as file:
    reader = PyPDF2.PdfFileReader(file)
    text = ''
    for page_num in range(reader.numPages):
        page = reader.getPage(page_num)
        text += page.extractText()

print(text)

Effortlessly convert PDF content into text format for easy manipulation and analysis!

Convert Image to text

import pytesseract as t
from PIL import Image
img = Image.open("photo.jpg")
text = t.image_to_string(img)
print(text)

Tip : Use the zip() function to iterate over multiple iterables simultaneously Example:

# Create two lists
names = ["John", "Mary", "Bob"]
ages = [30, 25, 40]

# Iterate over both lists using zip()
for name, age in zip(names, ages):
    print(f"{name} is {age} years old.")

Benefits: * Simplifies the process of iterating over multiple lists or tuples * Ensures that the elements from corresponding lists are aligned Language: Python
