Question

Does anyone know how I can find the version of a binary file that has been passed to my function?

I got the following code from this page:

def version(fpath):
    f = open(fpath, 'rb')

    s = f.read(1024)
    print s

    f.close()

However, this does not give me any useful output similar to what the mentioned website shows.

Edit: @BoazYaniv tells me that the file format plays in important part in this problem. This is a windows EXE file

Answer 1

We use this code to pull versions from one of our executables for use throughout other programs.

import win32api

try:
    info = win32api.GetFileVersionInfo('rpmsrv.exe', "\\")
    ms = info['FileVersionMS']
    ls = info['FileVersionLS']
    __version__ = "%d.%d.%d.%d" % (win32api.HIWORD(ms), win32api.LOWORD (ms),
                                 win32api.HIWORD (ls), win32api.LOWORD (ls))
except:
    __version__ = '5.1.1.000' # some appropriate default here.

— To encompass the comments —

This requires that the Windows Bindings for Python be installed. They’re available here: http://starship.python.net/~skippy/win32/. This also limits this solution to Windows platforms (which may or may not be an important factor in the final project).
