Hi,
I would like to remove certain lines from a log files. I had
some sed/awk scripts for this, but now, I want to use python
with its re module for this task.
Actually, I have two different log files. The first file looks
like:
...
'some text'
...

Hi Fabian,
I'm still a youngster in Python but I think I can help with the
extracting data from the log file part. As I'm seeing it right now,
the only character separating the numbers below is the space character.
You could try splitting all the lines by that character starting from
the NO
Can you safely assume that the lines you want to extract all contain
numbers, and that the lines you do not wish to extract do not contain
numbers?
If so, you could just use the Linux grep utility: grep '[0123456789]'
filename
Or, in Python:
import re
inf = file(your-filename-here.txt)
outf =

A more difficult log file looks like:

With my sed/awk/grep/gnuplot script I would extract the
values in the 'U-Mom' row using grep and print a certain
column (e.g. 'Max Res') to a file and print it with gnuplot.
Maybe I have to remove those '|' using sed before...

a fine solution component for the second problem
Use his solution like:
datafile = open(data_file_name, 'r')
for line in datafile:
if 'U-Mom' in line:
print float(line.split(|)[4])
datafile.close()
For the earlier problem:

Hi,
I actually want to extract the lines with the numbers, write
them to a file and finally use gnuplot for plotting them. A
nicer and more python way would be to extract those numbers,
write them into an array according to their column and plot
those

Coming from C++, using exceptions in this way still feels a bit creepy
to me, but I've been assured that this is very pythonic, and I'm slowly
adopting this style in my python code.
Parsing the line can be easy too:
