Python Find Type Of File

There are Python libraries that can recognize files based on their content (usually a header / magic number) and that don't rely on the file name or extension. If you're addressing many different file types, you can use. That's just a Python binding for the well-established magic library. This has a good reputation and (small endorsement) in the limited use I've made of it, it has been solid. There are also libraries for more specialized file types.

For example, the Python standard library has the module that does the same thing just for image file types. The library provides the functionality you need. You can install the library with pip install python-magic and use it as follows: >>>import magic >>>magic.from_file('iceland.jpg') 'JPEG image data, JFIF standard 1.01' >>>magic.from_file('iceland.jpg', mime=True) 'image/jpeg' >>>magic.

Thus, this does the same thing as the subprocess/shell-based answers, but without that overhead.

Python doesn’t depend on the underlying operating system’s notion of text files; all the processing is done by Python. The type of file object. How can I use python to list the filenames of all FASTQ files? Use os.listdir()? But how to specify on FASTQ file? To find files with a specific extension.
