How to enumerate and download attachments to a list item

[nopslider]

Hello,

This is a usage question rather than an issue per se. I'm attempting to download all attachments for a given list item. Here's my code so far:

if ctx_auth.acquire_token_for_app(client_id=clientid,client_secret=clientsecret:
    ctx = ClientContext("https://<removed>.sharepoint.com", ctx_auth)

    list_obj = ctx.web.lists.get_by_title("List title")
    items = list_obj.get_items(CamlQuery.create_all_items_query()) 
    ctx.execute_query()
    for item in items:
        if item.properties['Attachments']:
            #how do I download all attachments here??

else:
        print(ctx_auth.get_last_error())

Any help you could give would be most appreciated.

Greetings!

Here is an updated example:

list_obj = ctx.web.lists.get_by_title(list_title)
items = list_obj.get_items(CamlQuery.create_all_items_query())
ctx.execute_query()
for item in items:
    if item.properties['Attachments']:  # 1. determine whether ListItem contains attachments
        # 2. Explicitly load attachments for ListItem     
        attachment_files = item.attachmentFiles
        ctx.load(attachment_files)
        ctx.execute_query()
        # 3. Enumerate and save attachments
        for attachment_file in attachment_files:
            download_file_name = os.path.join(download_path, os.path.basename(attachment_file.properties["FileName"]))
            with open(download_file_name, 'wb') as fh:
                content = attachment_file.read()
                fh.write(content)

Comments:

• ListItem.Attachments property allows only to determine whether ListItem contains attachments, it does not contain any attachments details, ListItem.AttachmentFiles navigation property does

• from a performance perspective, list items could be retrieved along with attachments via a single request, meaning the second request could be avoided
