Many file formats have "magic bytes" that you can use for that purpose. https://en.wikipedia.org/wiki/List_of_file_signatures
Also, UNIX systems ship with a command called "file" which inspects a file's leading data for such magic numbers to identify their content. And there's a library called libmagic [1,2] which does this work, and there's a PyPI package called python-magic [3] for using this from Python, not to mention various other PyPI modules [4].
