Key Difference – R vs Python
R yog cov lus hais lus siab thiab ib puag ncig software rau kev txheeb xyuas thiab tshaj tawm. Python yog ib hom lus hais lus siab, dav dav. Yog li, qhov sib txawv tseem ceeb ntawm R thiab Python yog tias R yog ib hom lus qhia txog kev ua haujlwm thaum Python yog hom lus siv dav dav. R tuaj yeem siv rau kev suav lej, kev kawm tshuab, thiab kev txheeb xyuas cov ntaub ntawv. Python tuaj yeem siv rau kev kawm tshuab, kev tsim kho lub vev xaib, kev sib txuas lus, kev suav lej, thiab ntau ntxiv.
R yog dab tsi?
R yog hom lus programming thiab ib puag ncig software rau kev txheeb xyuas kev txheeb cais, tshaj tawm rau sawv cev cov duab. Qhov txiaj ntsig tseem ceeb ntawm kev siv R yog tias nws tuaj yeem siv los siv cov ntsiab lus txheeb cais xws li cov qauv kab thiab tsis yog kab, kev tshawb xyuas lub sij hawm series, pawg thiab lwm yam.
R yog ib hom lus txhais, yog li txhua kab yog nyeem ib tom qab los ntawm tus neeg txhais lus. Nws yog ib hom lus programming siab. Muaj ib tug hais kom ua-line txhais lus kom tus programmer tuaj yeem ncaj qha, nkag mus rau cov lus txib hauv kab hais kom ua. RStudio yog qhov sib koom ua ke Kev Txhim Kho Ib puag ncig (IDE) ua kom R programming yooj yim dua. Nws suav nrog code editor, debugging thiab visualization cov cuab yeej. Kuj tseem muaj cov pob khoom xws li ggplot2 thiab dplyr uas txuas ntxiv R nta ntxiv.
Thaum programming, nws yog qhov tsim nyog khaws cov txiaj ntsig. R tuaj yeem khaws cov nqi sib txawv. Nws tuaj yeem khaws cov ntaub ntawv muaj txiaj ntsig xws li qhov tseeb thiab tsis tseeb. Nws tseem tuaj yeem khaws cov lej, cov cim, thiab cov lej nyuaj. R muaj cov ntaub ntawv sib txawv xws li vectors, npe, matrices, arrays, yam thiab cov ntaub ntawv thav ntawv. Ib lub vector tuaj yeem siv los khaws ntau tshaj ib lub ntsiab lus. Ib daim ntawv teev npe tuaj yeem muaj ntau yam ntaub ntawv sib txawv ntawm cov ntsiab lus xws li vectors lossis lwm daim ntawv teev npe. Lub matrix tuaj yeem siv los khaws cov ntaub ntawv ob sab. Arrays yog siv los khaws cov ntaub ntawv ntawm txhua qhov loj me. Cov xwm txheej yog cov khoom r-cov khoom uas tsim los siv vector. Cov ntaub ntawv thav duab yog siv los khaws cov ntaub ntawv tabular cov khoom. Cov no yog cov ntaub ntawv tseem ceeb hauv R.
Nws tuaj yeem nyeem thiab sau rau hauv ntau hom ntaub ntawv xws li csv, excel, xml thiab JSON siv R. Nws tuaj yeem ua ke nrog cov ntaub ntawv xws li MySQL, Oracle, thiab lwm yam. Nws yog feem ntau siv rau kev txheeb cais, cov ntaub ntawv analytics, thiab machine learning.
Python yog dab tsi?
Python yog qib siab, cov hom phiaj dav dav dav dav. Nws yog tus ntoo khaub lig-platform thiab qhib qhov chaw. Nws yog ib qho ntawm cov lus programming nrov tshaj plaws rau cov neeg pib tshiab vim nws qhov yooj yim. Cov kev pab cuam python tau yooj yim nyeem, sau, sim thiab debug. Zoo ib yam li R, Python kuj yog ib hom lus txhais. Tus programmer tuaj yeem muab cov lus txib ncaj qha siv kab hais kom ua lossis siv tau IDE. Qhov feem ntau IDE rau Python yog PyCharm thiab dab noj hnub. Lawv muaj cov code editor, debugging nta, thiab lwm yam los tsim Python daim ntaub ntawv.
Cov ntaub ntawv sib txawv tuaj yeem khaws cia siv Python. Lawv tuaj yeem yog cov lej lossis cov hlua. Python txhawb nqa cov qauv ntaub ntawv xws li cov npe, tuples, thiab phau ntawv txhais lus. Ib daim ntawv tuaj yeem siv los khaws ntau cov ntaub ntawv ntawm ntau hom. Ib daim ntawv tuaj yeem hloov tau yog li nws tuaj yeem hloov pauv. Ib tug tuple kuj yog siv los khaws ntau yam khoom ntawm tib hom. Ib tug tuple yog ib yam khoom Python tsis tuaj yeem hloov tau. Cov phau ntawv txhais lus yog siv los khaws cov yuam sij, tus nqi khub. Cov no yog cov ntaub ntawv tseem ceeb hauv Python.
Python tuaj yeem siv los ua Graphical User Interfaces thiab tuaj yeem ua ke nrog cov ntaub ntawv xws li MySQL, MSSQL, thiab lwm yam. Nws muaj txiaj ntsig rau ntau yam kev siv. Nws tuaj yeem siv rau kev kawm tshuab, kev tsim kho lub vev xaib, kev sib txuas lus, kev tshawb fawb suav, automation, natural language processing thiab ntau yam ntxiv.
Dab tsi zoo sib xws ntawm R thiab Python?
