8. Indlela yokuvula iFayile ye-CSV kwiSofthiwe yoHlalutyo lweNkcazo - IiNgcebiso eziGqwesileyo

Ukuvula ifayile ye-CSV kwisoftware yohlalutyo lwamanani, kubalulekile ukulandela la manyathelo alandelayo:

1. Vula isoftware yohlalutyo lwezibalo ozikhethele yona. Eminye imizekelo eqhelekileyo ibandakanya i-R, iPython enelayibrari yePandas, i-SPSS, okanye i-Excel.

2. Kwibar yemenyu yesoftware, fumana inketho ethi "Vula" okanye "Ngenisa" kwaye ucofe kuyo.

3. Kwibhokisi yencoko yababini evelayo, yiya kwindawo yefayile ye-CSV ofuna ukuyivula. Khetha ifayile kwaye ucofe "Vula."

4. Qinisekisa ukuba isoftwe iqaphela uhlobo lwefayile njenge CSV. Ukuba akunjalo, unokufuna ukuyichaza ngesandla ngokukhetha u-“CSV” okanye “Icomma Delimited” kwibhokisi yencoko yababini.

5. Qinisekisa ukuba useto lwefomathi lufanelekile. Ngokuqhelekileyo, isoftware iya kuzibona ngokuzenzekelayo i-comma delimiter esetyenziswe kwifayile ye-CSV, kodwa ukuba akunjalo, qiniseka ukuba ukhethe "I-Comma" njenge-delimiter.

6. Emva koko unokukhetha ukukhetha uhlobo lwedatha kwikholamu nganye. Oku kuluncedo ukuba ufuna ukuqinisekisa ukuba idatha itolikwa ngokuchanekileyo. Umzekelo, ukuba unoluhlu lwemihla, unokufuna ukukhetha uhlobo lwedatha "Umhla" ukuqinisekisa ukuba itolikwa ngokuchanekileyo.

7. Ekugqibeleni, nqakraza "Kulungile" okanye "Ngenisa" ukuvula ifayile ye-CSV kwi-software yohlalutyo lwamanani. Isofthiwe kufuneka ilayishe idatha kwifayile ye-CSV kwaye ibonise kwitafile okanye kwifomathi efanelekileyo ngokuxhomekeke kwiprogram esetyenzisiweyo.

9. Ukukhupha kunye nokuguqula idatha emva kokuvula ifayile ye-CSV

Emva kokuvula ifayile ye-CSV, kufuneka wenze izenzo ezithile ukuze ukhuphe kwaye usebenzise idatha equlethwe kuyo. Apha ngezantsi kukho amanyathelo ekufuneka uwalandele:

Inyathelo loku-1: Thatha ngaphandle ithala leencwadi lePandas: Qinisekisa ukuba unayo ilayibrari yePandas efakwe kwindawo yakho yenkqubo. Emva koko, thatha ngaphandle ithala leencwadi usebenzisa le khowudi ilandelayo:

import pandas as pd

Inyathelo 2: Funda ifayile ye-CSV: Sebenzisa umsebenzi pd.read_csv() ukufunda ifayile ye-CSV kwaye ugcine idatha kwinto yeSakhelo seDatha. Umzekelo:

df = pd.read_csv('archivo.csv')

Inyathelo 3: Qhuba idatha: Nje ukuba idatha ilayishwe kwiDathaFrame, unokwenza imisebenzi eyahlukeneyo yokukhohlisa idatha. Ezinye izenzo eziqhelekileyo ziquka:

1. Sebenzisa amathala eencwadi athile: Amathala eencwadi angqale ukwenza iifayile ze-CSV, ezifana pandas kwiPython, baququzelela ukusetyenzwa kwedatha kunye nohlalutyo. La mathala eencwadi abonelela ngeendlela eziphuculweyo ezinokukhawulezisa ngokubonakalayo ukuvula kunye nokukhohlisa iifayile ze-CSV.
2. Chaza ifomathi ngokuchanekileyo: Xa uvula ifayile ye-CSV, kubalulekile ukucacisa ngokuchanekileyo ifomathi yedatha. Qinisekisa ukuseta i-delimiter efanelekileyo (ikoma, isemicolon, ithebhu, njl.njl.) kunye nomlinganiswa wokucaphula ukuba kuyimfuneko. Ezi nkcukacha zibalulekile ekuvuleni ifayile ngokuchanekileyo kunye nokuphepha iimpazamo zokutolika idatha.
3. Lawula ngokufanelekileyo iiheader: Ukuba ifayile ye-CSV iqulethe iiheader kumgca wokuqala, qiniseka ukuba uyiphatha ngokuchanekileyo xa uvula ifayile. Kusenokufuneka ukuba ungayihoyi i-header ngexesha lokucubungula okanye ukuzisebenzisa njengamagama eekholamu kwisakhiwo sedatha, kuxhomekeke kwiimfuno zakho. Ukuthathela ingqalelo oku kuya kuthintela iingxaki ekutolikeni idatha.

Ngamafutshane, ukuvula ifayile ye-CSV ngumsebenzi olula kodwa obaluleke kakhulu. Kulo lonke eli nqaku, sihlolisise iindlela ezahlukeneyo onokuzisebenzisa ukuvula nokufunda iifayile ze-CSV kwiindawo ezahlukeneyo, ezifana ne-Excel, i-Python kunye ne-SQL. Ukongeza, sixoxe ngokubaluleka kokuqonda ifomathi ye-CSV, ukwakheka kwayo kunye neempawu zayo.

Ngokuqonda indlela yokuvula ifayile ye-CSV ngokufanelekileyo, uya kukwazi ukufikelela kwiimali ezinkulu zedatha ngokufanelekileyo nangokuchanekileyo. Ingaba usebenza kuhlalutyo lwedatha, ukufuduka kolwazi, okanye nawuphi na omnye umsebenzi onxulumene nokulungiswa kwedatha, olu lwazi luya kukunceda kakuhle.

Ngalo lonke ixesha khumbula ukujonga umgangatho kunye nemfezeko yedatha yakho ye-CSV, uqinisekise ukuba ifomathwe kakuhle kwaye icwangciswe kakuhle phambi kokuba uqalise nayiphi na inkqubo yokukhohlisa. Kwakhona, gcina engqondweni ezona zenzo zibalaseleyo kunye neengqwalasela ezongezelelweyo esizikhankanyileyo ukuqinisekisa iziphumo ezizezona.

Ukuqukumbela, ukuvula nokuphatha iifayile ze-CSV kunokuba yinkqubo elula, kodwa kubalulekile ukulawula le nkalo esisiseko yokuguqulwa kwedatha ukufezekisa umsebenzi osebenzayo kunye nomgangatho. Ngolwazi oluchanekileyo kunye nezixhobo, uya kuba nako ukwenza uninzi lolwazi oluqulethwe kwiifayile ze-CSV, kwaye uthathe ithuba lokukwazi kwabo ngokupheleleyo. kwiiprojekthi zakho iingcali.
