How to horizontally align and display images side-by-side in an email using Python? - shantanu97 - Feb-22-2023

How can I horizontally align and display two images side-by-side using Python and HTML in an email? I've tried adding the images using HTML code, but they're currently being displayed vertically instead of horizontally. I'm not sure what I'm doing wrong, and I've already tried a few different approaches, but none of them seem to be working. Can someone help me modify my code to display the images responsively, side by side? It seems that changes need to be made to the current below HTML code. Full code also below.

html_text = body + '<html><body><br>'
    for i, image in enumerate(images):
        html_text = body + '<html><body><br><table border="0" cellspacing="0" cellpadding="0">'
        number_of_columns = 2 # set the number of columns here
        number_of_rows = (len(images) + number_of_columns - 1) // number_of_columns
        for row in range(number_of_rows):
            html_text += "<tr>"
            for col in range(number_of_columns):
                i = row * number_of_columns + col
                if i >= len(images):
                    break
                base = os.path.basename(images[i])
                image_without_extension = os.path.splitext(base)[0]
                html_text += "<td style='vertical-align: top;'>" + image_without_extension + ":<br><img src='cid:image{}' width='100' height='100'></td>".format(i)
                html_text += "</tr>"
        html_text += """</table><br><br>
                    Best,
                    <br>

    text = MIMEText(html_text, 'html')
