Python Data Types . Cov ntaub ntawv hom yog kev faib los yog categorization ntawm cov ntaub ntawv cov khoom. Cov ntaub ntawv hom sawv cev rau ib yam khoom muaj nqis uas txiav txim siab seb cov haujlwm twg tuaj yeem ua tau rau qhov ntawd cov ntaub ntawv . Numeric, non-numeric thiab Boolean (tseeb/false) cov ntaub ntawv yog feem ntau siv hom ntaub ntawv.
Ib yam li ntawd, koj tuaj yeem nug, yam khoom hom ntawv txhais li cas hauv Python?
Txhua lub ndarray muaj qhov cuam tshuam hom ntaub ntawv (dtype) khoom . Qhov no cov ntaub ntawv hom khoom (dtype) qhia peb txog qhov layout ntawm array. Qhov no txhais tau tias nws muab peb cov ntaub ntawv hais txog: Hom ntawm cov ntaub ntawv (integer, ntab, Python object etc.) if the hom ntaub ntawv yog ib tug sub-array, nws zoo li cas thiab hom ntaub ntawv.
hom () hauv Python yog dab tsi? Python | hom() muaj nuj nqi. hom() txoj kev rov qab chav kawm hom ntawm qhov kev sib cav (khoom) dhau li parameter. hom() muaj nuj nqi feem ntau yog siv rau kev debugging lub hom phiaj. Yog peb sib cav hom (npe, bases, dict) dhau lawm, nws rov los tshiab hom khoom.
Yog li, puas yog kev ua haujlwm hom ntaub ntawv hauv Python?
Python Cov lej Lawv txhais tau tias yog int, ntab thiab cov chav kawm nyuaj hauv Python . Peb tuaj yeem siv tau hom () muaj nuj nqi kom paub qhov twg a sib txawv los yog tus nqi belongs rau thiab lub isinstance() muaj nuj nqi los xyuas seb ib yam khoom twg yog nyob rau hauv ib chav kawm.
Dtype yog dab tsi?
Cov ntaub ntawv hom khoom ( dtype ua ) Cov ntaub ntawv hom khoom (ib qho piv txwv ntawm numpy. dtype ua chav kawm) piav qhia txog yuav ua li cas cov bytes nyob rau hauv qhov chaw ruaj khov ntawm lub cim xeeb sib raug rau cov khoom array yuav tsum tau txhais. Nws piav qhia txog cov ntaub ntawv hauv qab no: Hom ntaub ntawv (tus lej, ntab, Python khoom, thiab lwm yam)

Cov ntaub ntawv hom thiab cov qauv ntaub ntawv yog dab tsi?
Cov qauv ntaub ntawv yog ib txoj hauv kev piav qhia txog ib txoj hauv kev los npaj cov ntaub ntawv kom ua haujlwm andalogrithms tuaj yeem siv tau yooj yim dua. Ib hom ntaub ntawv piav qhia txog cov ntaub ntawv uas txhua tus sib koom ua ke. Piv txwv li tus lej cov ntaub ntawv hom piav qhia txhua tus lej uas lub khoos phis tawj tuaj yeem ua tau
Dab tsi yog lub hom phiaj ntawm delimiters nyob rau hauv cov ntawv sau npe ob hom ntawv cov ntaub ntawv delimiters?
Cov ntaub ntawv delimited yog cov ntawv nyeem siv los khaws cov ntaub ntawv, uas txhua kab sawv cev rau ib phau ntawv, tuam txhab, lossis lwm yam, thiab txhua kab muaj cov teb sib cais los ntawm tus lej
Dab tsi yog hom ntaub ntawv phau ntawv txhais lus?
Muaj ob hom ntaub ntawv phau ntawv txhais lus – Active thiab Passive
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Hom ntaub ntawv twg ntawm Hadoop tso cai rau columnar cov ntaub ntawv cia hom?
Columnar ntaub ntawv tawm tswv yim (Parquet, RFile) Qhov tseeb hotness nyob rau hauv cov ntaub ntawv tawm tswv yim rau Hadoop iscolumnar cov ntaub ntawv cia. Yeej qhov no txhais tau hais tias tsis yog cia li khaws cov kab ntawm cov ntaub ntawv nyob ib sab rau ib leeg koj kuj khaws cov kab ntawv nyob ib sab. Yog li datasets tau muab faib ua ob qho tib si horizontally thiab vertically
