writing on file not until the end

[Alexzive]

Hello,
I am a newby with python. I wrote the following code to extract a text
from a file and write it to another file:

linestring = open(path, 'r').read() #read all the inp file in
linestring

i=linestring.index("*NODE")
i=linestring.index("E",i)
e=linestring.index("*",i+10)
textN = linestring[i+2:e-1] # crop the ELement+nodes list
Nfile = open("N.txt", "w")
Nfile.write(textN)

unfortunately when I check N.txt some lines are missing (it only crop
until "57, 0.231749688431, 0.0405121944142" but I espect the final
line to be "242, 0.2979675, 0.224605896461". I check textN and it has
all the lines until "242..")

when I try Nfile.write(textN) again it writes some more lines but
still not all!
what is wrong whit this?

Many thanks for your help!
Alex

the original file to crop (in path) looks like this:

*HEADING
ABAQUS-style file created by OOF2 on 2009-03-05 03:23:49.204607 from a

[Rhodri James]

Hello,
I am a newby with python. I wrote the following code to extract a text
from a file and write it to another file:

linestring = open(path, 'r').read() #read all the inp file in
linestring

i=linestring.index("*NODE")
i=linestring.index("E",i)
e=linestring.index("*",i+10)
textN = linestring[i+2:e-1] # crop the ELement+nodes list
Nfile = open("N.txt", "w")
Nfile.write(textN)

unfortunately when I check N.txt some lines are missing (it only crop
until "57, 0.231749688431, 0.0405121944142" but I espect the final
line to be "242, 0.2979675, 0.224605896461". I check textN and it has
all the lines until "242..")

when I try Nfile.write(textN) again it writes some more lines but
still not all!
what is wrong whit this?

Cutting and pasting (and substituting the sample file for `path`),
it works for me on Python 2.6.2 (Ubuntu Linux). It must be something
to do with the context you're calling the code in. Are you checking
the output before the program has finished running or something?

Many thanks for your help!

the original file to crop (in path) looks like this:

<snip>

Is there a reason you used e-1 instead of e in the slice? That's going
to chop off the last newline. And in some (broken) text viewers, you
might not see the partial line. Also, it'll behave a bit different in
Windows than in one of the Unix variants, due to newline being
represented by two characters instead of one.

e=linestring.index("*",i+10)
textN = linestring[i+2:e-1] # crop the ELement+nodes list

Do you check the contents of the resulting file by feeding it to another
program?

There's a "t" at the start of the line after the last line you claim to see,
so maybe your input file is corrupt and your reader stumbles over that line.

Thank you all for replying.

- yes, I oversaw the "t" at "60, 0.250420691759, 0.0399644155193". I
then removed it for the following tests
- changing from "e-1" to "e" apparently solved the problem, BUT I then
realized it was just because a second access to the file (still open)
seems to be the real solution --> after Nfile.close() e retrying with
"e" instead of "e-1" the problem is still there.
- I also tryied to inizialize e and i to zero --> nothing changes
- until now, the only solution which works is to repeat the code while
the file is still open, which means a quite redundant code:

linestring = open(path, 'r').read()
i=linestring.index("*NODE")
i=linestring.index("E",i)
e=linestring.index("*",i+10)
textN = linestring[i+2:e-1] # crop the ELement+nodes list
Nfile = open("N.txt", "w")
Nfile.write(textN)

linestring = open(path, 'r').read()
i=linestring.index("*NODE")
i=linestring.index("E",i)
e=linestring.index("*",i+10)
textN = linestring[i+2:e-1] # crop the ELement+nodes list

Is this the complete script? The only effect of the second copy of your code
above is that it implicitly closes the first Nfile. Otherwise it is cargo
cult.

Others had already mentioned close(), but I didn't bother, since it
would be automatically closed when you exited the function, or finished
the script. I never dreamed you were running all this from the
interpreter. If so, why didn't you copy the prompts?

The close is best done explicitly, but it is implicit when the Nfile
goes out of scope, or gets reassigned (like the new open).

However, the bug I described is still there. Study the following, and
try it:

def test():
buf = "abcdefghijklmnopqrstg000"
i = buf.index("d")
e = buf.index("g", i+10)
buf2 = buf[i+2:e-1]
print buf2

running it produces the string:

fghijklmnopqrs

Notice the 't' is missing. If you're deliberately doing that, fine.
But I doubt it.
