What is the way to get file type from base64 string?
- I need a solution which will work on Windows and Linux(Centos7)
E.G.: This is string ; eHh4eHh4 which is = to a text file with xxxxxx inside.
If websites can do this, I guess it is possible to do it in python:

data = 'iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNk+P+/HgAFhAJ/wlseKgAAAABJRU5ErkJggg=='6

bytesData = io.BytesIO()8
bytesData.write(base64.b64decode(data))9
bytesData.seek(0) # Jump to the beginning of the file-like interface to read all content!10
print(magic.from_buffer(bytesData.read()))11
Out:
