filetype 1.2.0
Infer file type and MIME type of any file/buffer. No external dependencies.

Keywords: file libmagic magic infer numbers magicnumbers discovery mime type kind

filetype.py |Build Status| |PyPI| |Pyversions| |API|
====================================================

Small and dependency free `Python`_ package to infer file type and MIME
type checking the `magic numbers`_ signature of a file or buffer.

This is a Python port from `filetype`_ Go package.

Features
--------

-  Simple and friendly API
-  Supports a `wide range`_ of file types
-  Provides file extension and MIME type inference
-  File discovery by extension or MIME type
-  File discovery by kind (image, video, audio…)
-  `Pluggable`_: add new custom type matchers
-  `Fast`_, even processing large files
-  Only first 261 bytes representing the max file header is required, so
   you can just `pass a list of bytes`_
-  Dependency free (just Python code, no C extensions, no libmagic
   bindings)
-  Cross-platform file recognition

Installation
------------

::

    pip install filetype

API
---

See `annotated API reference`_.

Examples
--------

Simple file type checking
^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: python

    import filetype

    def main():
        kind = filetype.guess('tests/fixtures/sample.jpg')
        if kind is None:
            print('Cannot guess file type!')
            return

        print('File extension: %s' % kind.extension)
        print('File MIME type: %s' % kind.mime)

    if __name__ == '__main__':
        main()
