Qhov tseem ceeb ntawm Python Libraries hauv Data Science
Nyob rau hauv lub ntiaj teb loj heev ntawm programming, Python tau sawv tawm los ua hom lus xaiv rau kev tshawb fawb cov ntaub ntawv. Yog vim li cas? Nws cov tsev qiv ntawv muaj zog tshwj xeeb rau kev txheeb xyuas cov ntaub ntawv. Hoob "Discover Python cov tsev qiv ntawv rau Cov Ntaub Ntawv Kev Tshawb Fawb" ntawm OpenClassrooms muab koj ib tug tob rau hauv lub ecosystem no.
Los ntawm thawj cov qauv, koj yuav raug qhia txog cov kev coj ua zoo thiab cov kev paub tseem ceeb kom ua tiav koj cov kev txheeb xyuas nrog Python. Koj yuav pom tias cov tsev qiv ntawv xws li NumPy, Pandas, Matplotlib thiab Seaborn tuaj yeem hloov koj txoj hauv kev rau cov ntaub ntawv. Cov cuab yeej no yuav tso cai rau koj tshawb nrhiav, tswj xyuas thiab pom koj cov ntaub ntawv nrog kev ua haujlwm tsis sib xws thiab raug.
Tab sis tsis yog tag nrho. Koj tseem yuav kawm txog qhov tseem ceeb ntawm kev ua raws qee cov cai yooj yim thaum ua cov ntaub ntawv ntau. Cov hauv paus ntsiab lus no yuav pab koj kom ntseeg tau qhov tseeb thiab qhov tseeb ntawm koj qhov kev tshuaj ntsuam.
Hauv luv luv, chav kawm no yog kev caw kom dhia mus rau hauv lub ntiaj teb txaus nyiam ntawm cov ntaub ntawv tshawb fawb nrog Python. Txawm hais tias koj yog tus xav paub pib lossis tus kws tshaj lij tab tom nrhiav kom kho koj cov kev txawj ntse, chav kawm no yuav muab koj cov cuab yeej thiab cov tswv yim xav tau los ua kom tau zoo hauv thaj chaw.
Tshawb nrhiav Lub Hwj Chim ntawm Cov Ntaub Ntawv Ntiag Tug rau Kev Ntsuas Zoo
Thaum nws los txog rau kev tswj hwm thiab tshuaj xyuas cov ntaub ntawv tsim nyog, cov ntaub ntawv thav ntawv yog qhov tseem ceeb. Thiab ntawm cov cuab yeej muaj rau kev ua haujlwm nrog cov ntaub ntawv no, Pandas sawv tawm raws li tus qauv kub hauv Python ecosystem.
Cov chav kawm OpenClassrooms qhia koj ib kauj ruam hauv kev tsim koj thawj cov ntaub ntawv thav ntawv nrog Pandas. Cov txheej txheem ob-seem, zoo li lub rooj tso cai yooj yim manipulation ntawm cov ntaub ntawv, muab sorting, filtering, thiab aggregation muaj peev xwm. Koj yuav pom yuav ua li cas los tswj cov ntaub ntawv no kom rho tawm cov ntaub ntawv cuam tshuam, lim cov ntaub ntawv tshwj xeeb thiab txawm tias sib koom ua ke cov ntaub ntawv sib txawv.
Tab sis Pandas tsis txwv rau kev siv yooj yim. Lub tsev qiv ntawv kuj muaj cov cuab yeej muaj zog rau kev sib sau cov ntaub ntawv. Txawm hais tias koj xav ua haujlwm pab pawg, suav cov txheeb cais, lossis sib sau cov ntaub ntawv, Pandas muaj qhov koj xav tau.
Yuav kom ua tau zoo hauv cov ntaub ntawv kev tshawb fawb, nws tsis txaus kom paub algorithms lossis cov tswv yim tsom xam. Nws tsuas yog ib qho tseem ceeb heev kom paub cov cuab yeej uas tso cai rau koj los npaj thiab tsim cov ntaub ntawv. Nrog Pandas, koj muaj ib tug phooj ywg zoo kom tau raws li cov kev cov nyom ntawm cov ntaub ntawv niaj hnub science.
Daim Duab Qhia Dab Neeg nrog koj cov ntaub ntawv
Cov ntaub ntawv science tsis yog hais txog kev rho tawm thiab tswj cov ntaub ntawv. Ib qho kev ntxim nyiam tshaj plaws yog qhov muaj peev xwm pom cov ntaub ntawv no, hloov nws mus rau hauv cov duab sawv cev uas qhia ib zaj dab neeg. Nov yog qhov twg Matplotlib thiab Seaborn, ob ntawm Python cov tsev qiv ntawv nrov tshaj plaws pom, tuaj rau hauv kev ua si.
Cov chav kawm OpenClassrooms coj koj mus taug kev los ntawm kev xav ntawm cov ntaub ntawv pom nrog Python. Koj yuav kawm paub siv Matplotlib los tsim cov kab kos yooj yim, xws li kab kos duab, histograms, thiab cov phiaj xwm tawg. Txhua hom kab ntawv muaj nws lub ntsiab lus thiab cov ntsiab lus ntawm kev siv, thiab koj yuav raug coj los ntawm kev coj ua zoo tshaj plaws rau txhua qhov xwm txheej.
Tab sis lub visualization tsis nres ntawd. Seaborn, ua rau Matplotlib, muaj cov yam ntxwv siab heev rau kev tsim ntau txoj hauv kev zoo nkauj thiab ua kom pom kev zoo nkauj. Seb nws yog heatmaps, violin plots, los yog zaj duab xis khub, Seaborn ua rau nws yooj yim thiab intuitive.
