parsing a text file in python, c++, given specific format -

-

i have file in following format; parse in pyhton , c++ , extract number after impvarno: there lots of line in format.

sample.txt

start: abc pqr (ff_ggggg_confirm_tr):tc:20222,seqnum:86,impvarno:1000000008234436,id:12,oneid:66454,a/c:1,impvalue:905,impvar:25,actualvalue:905,actualvar:25,abc pqr xyz impquantity:0,pgb ncr yepp start: abc pqr (ff_ggggg_confirm_tr):tc:20222,seqnum:86,impvarno:1000000008234436,id:12,oneid:66454,a/c:1,impvalue:905,impvar:25,actualvalue:905,actualvar:25,abc pqr xyz impquantity:0,pgb ncr yepp start: abc pqr (ff_ggggg_confirm_tr):tc:20222,seqnum:86,impvarno:1000000008234436,id:12,oneid:66454,a/c:1,impvalue:905,impvar:25,actualvalue:905,actualvar:25,abc pqr xyz impquantity:0,pgb ncr yepp start: abc pqr (ff_ggggg_confirm_tr):tc:20222,seqnum:86,impvarno:1000000008234436,id:12,oneid:66454,a/c:1,impvalue:905,impvar:25,actualvalue:905,actualvar:25,abc pqr xyz impquantity:0,pgb ncr yepp

so wrote following code:

#!/usr/bin/env python  import sys import re  hand = open('newlogfile.txt') line in hand:     r = re.compile("exorderno:(\d+),")      print r  

import re  open('newlogfile.txt') f:     r = re.compile("impvarno:(\d+),")     line in f:         inp = r.findall(line)         if inp:             print(float(inp[0]))  1000000008234436 1000000008234436 1000000008234436 1000000008234436

if line starts same thing:

   import re      open('newlogfile.txt') f:         r = re.compile("impvarno:(\d+),")         line in f:             if line.startswith("(ff_ggggg_confirm_tr)"):                 print(r.findall(line))

i struggling on how find correct way specify save path (or repository) when calling function savefig in matplotlib or pylab. i tried several syntaxes, everytime python console returns : filenotfounderror: [errno 2] no such file or directory: '../mydocs/resource/frames/myimage.png' currently, have written following : pylab.savefig('../mydocs/resource/frames/myimage.png') does know how it? thanks in advance! the tilde operator , variable $home entered strings , therefore not function while saving. have provide either relative path (as did) or provide full path. eg. pylab.savefig("/home/username/desktop/myfig.png") .
