How do i get my code to only select a .csv attachment and not the image from within the email txt?

I currently have the below code that works perfectly if the email is blank but if it comes as part of a chain and it has images (ie company logos in peoples signature etc) then it will only find those. How do i filter it to only select the .csv?

    import win32com.client
    import os
    import time
    outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
    folder = outlook.Folders.Item("myemail@gmail.com")
    inbox = folder.Folders.Item("Inbox")
    msg = inbox.Items
    msgs = msg.GetLast()
    print (msgs)
    print (msgs.Subject)

    Filter = "[SenderEmailAddress] = 'senderemail@gmail.com'"
    Filter = ("@SQL=" + chr(34) + "urn:schemas:httpmail:subject" +
                        chr(34) + " Like 'subjectofemail' AND " +
                        chr(34) + "urn:schemas:httpmail:hasattachment" +
                        chr(34) + "=1")

    Items = inbox.Items.Restrict(Filter)
    for Item in Items:
        for attachment in Item.Attachments:
            print(attachment.FileName)
            attachment.SaveAsFile("U:\Downloads\Foldername\Otherfolder\\" + attachment.FileName)
      
            timestr = time.strftime("%Y%m%d")

            old_name = r"U:\Downloads\Foldername\Otherfolder\\attachmentfilename.csv"
            new_name = r"U:\Downloads\Foldername\Otherfolder\\attachmentfilename " + timestr + ".csv"

            os.rename(old_name, new_name)

I have tried a few things ive seen on here but i am very new and have basically created this code from snippets of code i found and got it working with trial and error so im not sure what im doing really. Im trying to learn as i go but assume i need an ELI5 if possible. Thanks

There are two kind of attachments that should be detected:

1. Attachments with a specific extension - .csv. You can filter them by checking the Attachment.FileName property like you have already figured it out.

2. Embedded images that are used for the message body markup. You can check the message body content for the PR_ATTACH_CONTENT_ID MAPI property value (the DASL name is "http://schemas.microsoft.com/mapi/proptag/0x3712001F"). Use the Attachment.PropertyAccessor.GetProperty method for retrieving the value and then check the attachment in the message body using the src attribute that matches the value of PR_ATTACH_CONTENT_ID set on the attachment. PR_ATTACH_CONTENT_ID corresponds to the Content-ID MIME header when the message is sent.
