encode_file

Encodes a file into a multipart/form-data byte sequence using a specified boundary and key. The function determines the content type based on the file's attributes or name and reads the file's content into the resulting byte list.

def encode_file(
    boundary: string,
    key: string,
    file: file-like object
) - > list

Encodes a file into a list of byte strings formatted as a multipart/form-data MIME part. This is used to prepare file uploads for HTTP requests by generating the necessary boundary markers, headers, and binary content.
