Old question, but just wanted to share the solution to this I came up with today. Searches for all emails with attachments and outputs the uid, sender, subject, and a formatted list of attachments. Edited relevant code to show how to format BODYSTRUCTURE:

    data   = mailobj.uid('fetch', mail_uid, '(BODYSTRUCTURE)')[1]
    struct = data[0].split()        
    list   = []                     #holds list of attachment filenames

    for j, k in enumerate(struct):
        if k == '("FILENAME"':
            count = 1
            val = struct[j + count]
            while val[-3] != '"':
                count += 1
                val += " " + struct[j + count]
            list.append(val[1:-3])
        elif k == '"FILENAME"':
            count = 1
            val = struct[j + count]
            while val[-1] != '"':
                count += 1
                val += " " + struct[j + count]
            list.append(val[1:-1])
