Sto cercando di usare difflib per produrre diff per due file di testo contenenti tweet. Ecco il codice:python difflib confronto file
#!/usr/bin/env python
# difflib_test
import difflib
file1 = open('/home/saad/Code/test/new_tweets', 'r')
file2 = open('/home/saad/PTITVProgs', 'r')
diff = difflib.context_diff(file1.readlines(), file2.readlines())
delta = ''.join(diff)
print delta
Ecco il file PTITVProgs
di testo:

Come puoi vedere confrontando rapidamente i due file di origine (PTITVProgs e new_tweets) che la differenza tra loro è i 3 tweet che erano il 7 aprile e 3 tweet il 3 aprile.
Voglio solo le linee in new_tweets
che non sono in PTITVProgs
per apparire nel diff.
Ma getta un po 'di testo che non voglio vedere. Non so cosa *** 1,7***
e *** 1,3***
nel supporto di uscita diff per ...? Qual è il modo corretto per ottenere solo le linee modificate??
non sono sicuro difflib è lo strumento giusto per il lavoro che si sta cercando di fare a tutti - è molto più lavoro (algoritmicamente parlando) per generare una differenza rispetto a fare solo un confronto di set. 'print set (fileA.readlines()). difference (set (fileB.readlines()))' –
