Unfortunately, Python offers much greater flexibility than Python in data
handling, and correspondingly more chances to shoot yourself in the foot.
I'm assuming it's *convenient* to have these data in binary form, otherwise
you could always write  a Fortran program to convert them into something
Python finds easier to deal with ...

I also presume it was written with FORMAT statements (sheesh, does Fortran
even USE those now, showing my age I'm afraid). Python can read a particular
number of bytes if you give read() a numeric argument, but if you don't it
just tries to gobble the whole file in a oner.

Otherwise you may have to look at the struct module, and that's too tricky
for a beginner.

 Steve
