Bug report

Bug description:

According to

, the use ofnargs='+' indicates that the original intention was to support passing multiple files and identifying their MIME types one by one

However, the current behavior only processes the first file. For example, running the following command:

> python mimetypes.py 1.pdf 1.pngtype: application/pdf encoding: None

only outputs the type information for1.pdf, while1.png is ignored.

CPython versions tested on:

3.14

Operating systems tested on:

Windows
