I want to download all the files from unread emails. But files with same name gets replaced somehow only one file name is showing.

CodePudding user response：

This is very much expected behavior. There can be only one file with a specific name in a specific folder. You will need to implement some logic to see if the file already exists, and rename it.

See below for a simple example:

import os


def autorename(filename):
    """recursive function to add " (copy)" to a filename if it already exists.
    """
    if os.path.isfile(filename):
        newfilename = f"{os.path.splitext(filename)[0]} (copy){os.path.splitext(filename)[1]}"
        return autorename(newfilename)
    else:
        return filename

For the os.path.splitext() part, see this answer.

EDIT

To add this to your code, you need to change this line:

attachment.SaveAsFile(os.path.join(path, str(attachment)))

to this:

attachment.SaveAsFile(autorename(os.path.join(path, str(attachment))))

so it generates a new filename if the file already exists
