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!

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
