Hauv Python , Tsis muaj lo lus tseem ceeb yog ib yam khoom, thiab nws yog ib hom ntaub ntawv ntawm chav kawm NoneType. Peb tuaj yeem muab Tsis muaj rau ib qho sib txawv , tab sis koj tsis tuaj yeem tsim lwm yamNoneType khoom.
Ntawm no, dab tsi yog hom ntaub ntawv hauv Python?
Basic Data Types hauv Python
- Cov lej.
- Floating-Point Numbers.
- Cov zauv.
- Cov hlua. Escape Sequences nyob rau hauv Strings. Raw Strings. Triple-quoted Strings.
- Hom Boolean, Boolean Ntsiab Lus, thiab "Qhov tseeb"
- Built-In muaj nuj nqi. lej. Hom Hloov. Iterables thiab Iterators. Cov ntaub ntawv sib xyaw. Chav Kawm, Tus Cwj Pwm, thiab Txoj Cai. Input/Output.
- Xaus.
Ib yam li ntawd, koj txhais li cas los ntawm kev sib txawv? Hauv programming, a sib txawv yog tus nqi ntawd ua tau hloov, nyob ntawm cov xwm txheej lossis cov ntaub ntawv dhau mus rau qhov kev zov me nyuam. Feem ntau, ob qho tib si tsis tu ncua thiab variables yog txhais raws li tej yam ntaub ntawv hom s.
Kuj Paub, tuple txhais li cas?
Hauv lej, a tuple yog ib daim ntawv teev npe finite (sequence) ntawm cov khoom. Ib n- tuple yog ib ntu (los yog orderlist) ntawm n cov ntsiab lus, qhov twg n yog ib tug tsis-negative integer. Muaj yog tsuas yog 0- tuple , ib ntu ntu, orempty tuple , raws li nws yog xa mus rau.
Koj txhais li cas los ntawm hom ntaub ntawv?
A hom ntaub ntawv yog a hom ntawm cov ntaub ntawv . Yog lawm, qhov ntawd yog qhov ncig txhais , thiab tseem tsis pab. Thaum cov khoos phis tawj khaws cia cov ntaub ntawv invariables, txhua sib txawv yuav tsum tau muab ib qho tshwj xeeb hom ntaub ntawv . Qee yam hom ntaub ntawv suav nrog integers, floatingpoint tooj, cim, hlua, thiab arrays.

Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
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
Ib qho chaw tsis muaj zog puas tuaj yeem muaj qhov chaw tsis muaj zog?
Hom chaw tsis muaj zog muaj qee qhov yuam sij. Nco tseg- Lub koom haum tsis muaj zog ib txwm muaj kev koom tes tag nrho tab sis lub koomhaum muaj zog yuav tsis muaj tag nrho kev koom tes.Weak entity yog nyob ntawm qhov chaw muaj zog kom ntseeg tau tias muaj qhov tsis muaj zog. Zoo li lub koom haum muaj zog, qhov tsis muaj zog tsis muaj qhov tseem ceeb, Nws muaj feem cuam tshuam kev ntxub ntxaug
Puas yog array yog cov qauv ntaub ntawv lossis hom ntaub ntawv?
Ib qho array yog homogeneous cov ntaub ntawv qauv (cov ntsiab lus muaj tib cov ntaub ntawv hom) uas khaws cov khoom sib txuas ntawm cov khoom sib txuas ua ke - faib rau hauv kev sib txuas ua ke.Txhua yam khoom ntawm cov array tuaj yeem nkag tau los ntawm kev siv nws tus lej (piv txwv li, index). Thaum koj tshaj tawm ib qho array, koj teem nws qhov loj me
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
