difflib - Pab rau xam deltas. Source code: Lib/ difflib .py. Qhov module no muab cov chav kawm thiab ua haujlwm rau kev sib piv cov sequences. Nws tuaj yeem siv tau piv txwv, piv txwv li cov ntaub ntawv, thiab tuaj yeem tsim cov ntaub ntawv sib txawv hauv ntau hom ntawv, suav nrog HTML thiab cov ntsiab lus thiab kev sib koom ua ke.

Raws li, Difflib SequenceMatcher ua haujlwm li cas?

SequenceMatcher yog ib chav kawm hloov tau yooj yim rau kev sib piv khub ntawm cov kab ke ntawm txhua hom, tsuav yog cov kab ke sib txuas yog hashable. Qhov yooj yim algorithm predates, thiab yog me ntsis fancier tshaj, ib tug algorithm luam tawm nyob rau hauv lub lig 1980's los ntawm Ratcliff thiab Obershelp nyob rau hauv lub hyperbolic lub npe "gestalt qauv txuam".

Tsis tas li, SequenceMatcher ua haujlwm li cas hauv Python? SequenceMatcher yog ib chav kawm muaj nyob rau hauv python module hu ua "difflib". Nws tuaj yeem siv los sib piv cov khub ntawm cov khoom siv sib txuas. Qhov no tsis tau txais qhov hloov kho tsawg kawg nkaus, tab sis nws zoo li yuav ua rau cov khoom sib tw uas "zoo" rau tib neeg. Tos ib pliag.

Cov lus nug tseem yog, Difflib Get_close_match ua haujlwm li cas?

difflib . get_close_match (lus, possibilities, n, cutoff) lees txais plaub yam uas n, txiav tawm yog xaiv tau. lo lus yog ib theem zuj zus uas ze qhov sib tw yog xav tau, possibilities yog ib daim ntawv teev cov sequences uas yuav phim lo lus.

Kuv yuav piv ob cov ntaub ntawv hauv Python li cas?

Yog tias lawv yog ob cov ntawv nyeem, ces koj tuaj yeem siv cov snippet no:

  1. f1=open("file1. txt", "r")
  2. f2=open("file2. txt", "r")
  3. rau kab 1 hauv f1:
  4. rau kab 2 hauv f2:
  5. yog line1==line2:
  6. print("SIB")
  7. lwm tus:
  8. print(kab 1 + kab 2)
