Phau ntawv cov ntaub ntawv (los yog phau ntawv ”, tag nrho cov ntaub ntawv qis) yog cov ntaub ntawv tsim los ntawm Jupyter Phau ntawv App, uas muaj ob lub computer code (piv txwv li. python ) thiab cov ntsiab lus nplua nuj (cov kab lus, qhov sib npaug, cov duab, txuas, thiab lwm yam …).
Raws li txoj cai, Jupyter phau ntawv yog dab tsi?
Cov Jupyter Phau Ntawv yog ib daim ntawv thov qhib lub vev xaib uas koj tuaj yeem siv los tsim thiab qhia cov ntaub ntawv uas muaj cov lej nyob, sib npaug, pom pom, thiab ntawv nyeem.
Tom qab ntawd, lo lus nug yog, dab tsi yog phau ntawv sau hauv cov ntaub ntawv tshawb fawb? Hauv cov ntaub ntawv science ntiaj teb, phau ntawv tau tshwm sim los ua ib qho tseem ceeb - lawv yog cov ntaub ntawv nquag tsim los ntawm tib neeg lossis pab pawg los sau thiab khiav cov lej, tso tawm cov txiaj ntsig, thiab qhia cov txiaj ntsig thiab kev pom. Zoo li txhua zaj dab neeg, a cov ntaub ntawv science notebook ua raws li ib qho qauv uas raug rau nws hom.
Hais txog qhov no, siv Jupyter phau ntawv hauv Python li cas?
Jupyter Interface Tsim ib qho tshiab phau ntawv , mus rau Tshiab thiab xaiv Phau ntawv - Python 2. Yog tias koj muaj lwm yam Jupyter Phau Ntawv ntawm koj qhov system uas koj xav tau siv , koj tuaj yeem nyem Upload thiab mus rau cov ntaub ntawv tshwj xeeb. Phau ntawv Tam sim no khiav yuav muaj lub cim ntsuab, thaum tsis khiav yuav grey.
Puas yog Jupyter notebook yog IDE?
Jupyter Phau Ntawv muab koj nrog ib qho yooj yim-rau-siv, sib tham sib cov ntaub ntawv kev tshawb fawb ib puag ncig thoob plaws ntau hom lus programming uas tsis tsuas yog ua haujlwm raws li ib qho IDE , tab sis kuj yog ib qho kev nthuav qhia lossis cov cuab yeej kev kawm. Nws zoo meej rau cov neeg uas nyuam qhuav pib nrog cov ntaub ntawv tshawb fawb!

Cov Ntawv Txhais Lus Cov Ntaub Ntawv yog RML cov qauv ntaub ntawv uas khaws cov ntsiab lus ntawm qib teb txog cov ntaub ntawv hauv ib qho system lossis cov tshuab. Thaum lub sij hawm qhov yuav tsum tau ua, lub hom phiaj tsis yog ntawm cov ntaub ntawv tiag tiag hauv cov ntaub ntawv lossis kev tsim qauv tsim nyog los siv cov khoom lag luam cov ntaub ntawv hauv cov ntaub ntawv
Dab tsi yog cov txiaj ntsig ntawm phau ntawv txhais lus cov ntaub ntawv?
Ib phau ntawv txhais lus tau tsim muaj tuaj yeem muab cov koom haum thiab kev lag luam ntau cov txiaj ntsig, suav nrog: Txhim kho cov ntaub ntawv zoo. Txhim kho kev ntseeg siab ntawm cov ntaub ntawv ncaj ncees. Txhim kho cov ntaub ntawv thiab kev tswj xyuas. Txo cov ntaub ntawv redundancy. Rov qab siv cov ntaub ntawv. Kev sib raug zoo ntawm kev siv cov ntaub ntawv. Kev txheeb xyuas cov ntaub ntawv yooj yim dua. Txhim kho kev txiav txim siab raws li cov ntaub ntawv zoo dua
