Get the MIME type in Python and determine the file format

How to get the MIME type of a file in Python. By doing this, you can change the behavior by judging the format of the input file.


import mimetypes
mime = mimetypes.guess_type(File path)
print(mime) # => (MIME type,Encode format)

That's it. In the encoding format part, if it is a file compressed with gzip, some value will appear, but basically it will be None.

Behavior changes depending on the file format

As a simple example, let's say you only accept Markdown files. If any other file is entered, an error message will be displayed.

import mimetypes
import sys

input = sys.argv[1]
mime = mimetypes.guess_type(input)

if mime[0] = "text/markdown":
    print("You're a Markdown file!")
    print("{mime}Type of file is over there!".format(mime=mime[0]))

When you run ...

$ python3
You're a Markdown file!
$ python3 fuga.jpg
image/jpeg type files are sick!
