import qrcode
from PIL import Image

# Function to generate a basic QR Code
def generate_basic_qr(data, file_name):
    '''
    Generates a basic QR Code.
    
    Parameters:
    data (str): The data to be encoded.
    file_name (str): The file name for the saved QR Code image.
    '''
    # Create qr code instance
    qr = qrcode.QRCode(
        version=1,  # controls the size of the QR Code
        error_correction=qrcode.constants.ERROR_CORRECT_L,  # controls the error correction used
        box_size=10,  # controls how many pixels each “box” of the QR code is
        border=4,  # controls how many boxes thick the border should be
    )

    # Add data to instance
    qr.add_data(data)
    qr.make(fit=True)

    # Create an image from the QR Code instance
    img = qr.make_image(fill='black', back_color='white')

    # Save it somewhere, change the extension as needed
    img.save(file_name)

# Function to generate a QR Code with logo
def generate_qr_with_logo(data, logo_path, file_name):
    '''
    Generates a QR Code with a logo embedded.
    
    Parameters:
    data (str): The data to be encoded.
    logo_path (str): The path to the logo to be embedded.
    file_name (str): The file name for the saved QR Code image.
    '''
    # Generate QR Code
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_H,
        box_size=10,
        border=4,
    )
    qr.add_data(data)
    qr.make(fit=True)
    qr_img = qr.make_image(fill='black', back_color='white')

    # Add logo to QR Code
    logo = Image.open(logo_path)
    logo.thumbnail((70, 70))  # Resize logo
    pos = ((qr_img.size[0] - logo.size[0]) // 2,
           (qr_img.size[1] - logo.size[1]) // 2)
    qr_img.paste(logo, pos)

    # Save image
    qr_img.save(file_name)

generate_basic_qr('https://example.com', 'basic_qr.png')
generate_qr_with_logo('https://example.com', 'logo.png', 'qr_with_logo.png')

### Code Output:

Two files will be created:

• basic_qr.png containing a basic QR code.
• qr_with_logo.png containing a QR code with a logo embedded at its center.

### Code Explanation:

This program is a deep dive into the powerful ways QR codes can be leveraged in programming. It makes use of the qrcode Python library and outlines two primary functions: generate_basic_qr and generate_qr_with_logo.

1. generate_basic_qr Function:

This function crafts a basic QR code from the specified data. It initiates a QRCode object with various parameters such as version, error correction level, box size, and border. The version parameter affects the size of the generated QR code, error_correction determines the level of error correction, box_size specifies the size of each ‘box’ in the QR code, and border specifies the width of the border around the QR code. After adding the data to the QRCode object and calling the make method with fit=True, it generates an image of the QR code using the make_image method and saves it to a file.

2. generate_qr_with_logo Function:

For situations where branding is key, this function embeds a logo within a QR code. It generates a QR code as described above, but with a higher level of error correction to accommodate the logo. The logo is opened, resized to fit within the QR code, and pasted at the center of the QR code image. The resultant image with the embedded logo is then saved to a file.

In essence, this program demonstrates not just the generation of QR codes but also showcases the flexibility of QR codes in accommodating additional elements like logos, making QR codes a powerful tool in a variety of coding and programming scenarios.
