You don't show any code so it's hard to say what is going on.
My guess is that your file contains spurious newlines and/or CRLF combinations.

Try opening the file in universal newline mode and see what happens?

with open("fortranfile.txt", "rU") as f:
    for line in f:
        print("LINE:", line)
