Hi all,
I have a text file containing such data ;
A B C
-------------------------------------------------------
-2.0100e-01 8.000e-02 8.000e-05
-2.0000e-01 0.000e+00 4.800e-04
-1.9900e-01 4.000e-02 1.600e-04
But I only need Section B, and I need to change the notation to ;
8.000e-02 = 0.08
0.000e+00 = 0.00
4.000e-02 = 0.04
Text file is approximately 10MB in size. I looked around to see if
there is a quick and dirty workaround but there are lots of modules,
lots of options.. I am confused.
Which module is most suitable for this task ?
You probably don't need anything but sys (to parse the command options)
and os (maybe).
open the file
for eachline
if one of the header lines, continue
separate out the part you want
print it, formatted as you like
Then just run the script with its stdout redirected, and you've got your
new file
The details depend on what your experience with Python is, and what
version of Python you're running.
