I don't know about Fortran. But for np.fromfile, it reads raw data without any header or footer. If you file has header (and hopefully you know how long is it), I believe you can skip the header by passing a open and seeked file to np.fromfile. If your file has footer, use the count parameter of np.fromfile. If you are not sure how long is header/footer. Do a experiment with 0. and observe the file using hex editor

| Dec 5, 2018 at 22:29 | comment | added | NoMansEyes | @albert Yes I've looked at that post. It addresses having the wrong datatype for the content of the array. However, I know that the data in the array is r8, so I know that the python datatype should be float64. | |

@VladimirF I'm sorry if my question wasn't clear. Perhaps I can rephrase. Why does np.fromfile(fname) return more values than are in the array? In may case, there should be 3090903 entries, but the result has 3090904 entries. And why are the values that it returns not equal to the values in the source array?
