python - Diffing two files while ignoring any missed lines -

-

i diffing 2 unsorted files , problem moment 1 of files gets line not present in other file, diff goes off. want write/print line not present , continue on.

import re f1=open("file1","r") f2=open("file2","r") f=open("output","w") test_lines=f1.readlines() correct_lines=f2.readlines()  test, correct in zip(sorted(test_lines), sorted(correct_lines)):     if test.strip().split("(")[0].replace(" ","").strip() != correct.strip().split("(")[0].replace(" ","").strip() , test!="\n":         print "oh no! expected %r; got %r." % (correct, test)     else:         towrite=correct + test         f.write(towrite)  else:     len_diff = len(test_lines) - len(correct_lines)     if len_diff > 0:         print "test file had data."     elif len_diff < 0:         print "test file had little data."     else:         print "everything correct!"

sample input

file1

 jack tom apple orange

file2

jack apple ape  mike

it print oh no! expected apple got ape , fail

according comments don't want line line comparison. think python's set best suited case. here snippet:

import re f1=open("file1","r") f2=open("file2","r") f=open("output","w") test_lines=f1.readlines() correct_lines=f2.readlines()  test_lines = set([l.strip().split("(")[0].replace(" ","").strip() l in test_lines]) correct_lines = set([l.strip().split("(")[0].replace(" ","").strip() l in correct_lines])  print "expected: ", correct_lines-test_lines     print "got: ", test_lines-correct_lines

output:

expected:  set(['mike', 'ape']) got:  set(['orange', 'tom'])

    Hi Admin,

    Automated text messages if your phone detects you're a long way from home, or discounted home internet, are just a few possible technology solutions to make New Zealanders "stay home to save lives".

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
