Reading file error

[satish]

Hi all,

I am writing a file by name "input" out, with a small python code below:

grid=open('input','w')
grid.write(' ')
grid.write('/*number_of_zone\n')
grid.write(' ')
grid.write('2\n')
grid.write(' ')
grid.write('/*zone_number 1\n')
grid.write(' ')
grid.write('quadratic 50 25 6 2\n')

Upon execution, I get the file "input" whose contents are as per below:

/*number_of_zone
2
/*zone_number 1
quadratic 50 25 6 2


Now, when I tried to read this through my fortran code I get the following
errors:

/*zone_number 1

Input/Output Error 153: Input file ended

In Procedure: in_and_out..read_input
At Line: 4472

Statement: List-Directed READ
Unit: 10
Connected To: Work File
Form: Formatted (contains List-Directed records)
Access: Sequential
Records Read : 2
Records Written: 2

End of diagnostics


Outline of fortran code:

SUBROUTINE read_input()
OPEN (15, FILE='input')
READ .....
......
CLOSE(15)
END SUBROUTINE read_input

Some part of the error is related to some "scratch file" with unit=10 that the
fortran code is generating, which, I don't want to pay attention to.

My main problem is that when I generate "input" without python and simply
write everything by opening the file manually in my editor and then execute
it with the same fortran code, I don't get any such strange errors and it
works perfectly fine. I am therefore, wondering if this has got to do
anything with python.


Can someone help ??


Thanks in advance


Best Regards,

Whats diff telling on those two files? And - to me it looks like more of a
fortran problem, anyway.

READ .....
......

And of course you suppressed all the critical information... The
declaration(s) of the variables and the actual READ statements you used.

Dump the two files in hex format and compare them -- maybe the
line endings are coming up differently which sets things off... Or the
EOF is marked differently...
