Thanks Rob,

I'v modified the test_3 like this:


    def test_3(self):
        f =3D open("test.dat", "wb")
        filesize =3D (b'b'*1000000)
        f.write(filesize)
        f.close()
        statinfo =3D os.stat("test.dat")
        self.assertEqual(statinfo.st_size, filesize)
   =20
I'm still getting AssertionError and the error says: 1000000 !=3Db'

Help appreciated.

T=20
