Here are 10 Python snippets demonstrating how to determine MIME types of files based on their extensions using the mimetypes library. Each snippet is separated by a delimiter.

Snippet 1: Determine MIME Type of a File

import mimetypes

file_path = 'example.txt'
mime_type, encoding = mimetypes.guess_type(file_path)

print(f"MIME type: {mime_type}, Encoding: {encoding}")

---

Snippet 2: Determine MIME Type for Multiple Files

import mimetypes

file_paths = ['document.pdf', 'image.jpg', 'audio.mp3']

for file_path in file_paths:
    mime_type, encoding = mimetypes.guess_type(file_path)
    print(f"File: {file_path}, MIME type: {mime_type}")

---

Snippet 3: Handling Unknown MIME Types

import mimetypes

file_path = 'unknown.xyz'
mime_type, encoding = mimetypes.guess_type(file_path)

if mime_type is None:
    print(f"The MIME type for '{file_path}' is unknown.")
else:
    print(f"MIME type: {mime_type}")

---

Snippet 4: Determine MIME Type of an Image File

import mimetypes

file_path = 'photo.png'
mime_type, encoding = mimetypes.guess_type(file_path)

print(f"File: {file_path}, MIME type: {mime_type}")

---

Snippet 5: Determine MIME Type of a Video File

import mimetypes

file_path = 'movie.mp4'
mime_type, encoding = mimetypes.guess_type(file_path)

print(f"File: {file_path}, MIME type: {mime_type}")

---

Snippet 6: Set MIME Type for Custom File Extensions

import mimetypes

# Add custom MIME type for .myext files
mimetypes.add_type('application/x-myext', '.myext')

file_path = 'example.myext'
mime_type, encoding = mimetypes.guess_type(file_path)

print(f"File: {file_path}, MIME type: {mime_type}")

---

Snippet 7: Get MIME Type of an HTML File

import mimetypes

file_path = 'index.html'
mime_type, encoding = mimetypes.guess_type(file_path)

print(f"File: {file_path}, MIME type: {mime_type}")

---

Snippet 8: Determine MIME Type of a Compressed File

import mimetypes

file_path = 'archive.zip'
mime_type, encoding = mimetypes.guess_type(file_path)

print(f"File: {file_path}, MIME type: {mime_type}")

---

Snippet 9: Determine MIME Type Based on URL

import mimetypes

url = 'http://example.com/image.jpg'
mime_type, encoding = mimetypes.guess_type(url)

print(f"URL: {url}, MIME type: {mime_type}")

---

Snippet 10: Guess MIME Type with Unknown Extension

import mimetypes

file_path = 'unknownfile.abc'
mime_type, encoding = mimetypes.guess_type(file_path)

if mime_type:
    print(f"File: {file_path}, MIME type: {mime_type}")
else:
    print(f"No MIME type could be determined for {file_path}.")
