About .pyi Files
PYI files are a type of Python stub file that provides type definitions for modules.
They are plain text files with the MIME type text/x-python and are not meant to be executed directly.
They contain only function signatures, variable types, and class definitions. This assists static type checkers and code editors to verify and improve code quality.
- Static Type Checking: They offer type hints used by tools like mypy to catch errors before runtime.
- Interface Definition: They act like header files in other programming languages by separating the interface from the implementation.
- Editor Support: They enhance auto-completion and intellisense in editors such as PyCharm and VS Code.
You can edit these files with any text editor.
Based on information from FilExt.com, PYI files are an essential tool for integrating robust type checking in Python projects.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
