Cov tus yuam sij qhia lub ntsiab ntawm lub phau ntawv txhais lus , tus nqi yog cov ntaub ntawv sib raug rau qhov muab tus yuam sij . Ntsiab tus nqi yog tshwj xeeb, i. e. nyob ntawd ua tau tsis yog ob cov yuam sij zoo ib yam hauv phau ntawv txhais lus.
Ntxiv mus, phau ntawv txhais lus puas tuaj yeem muaj tus yuam sij Python?
Python phau ntawv txhais lus tsis txhawb yuam sij dua . Ib txoj hauv kev yog khaws cov npe lossis teeb tsa hauv lub phau ntawv txhais lus . thiab koj yuav tau txais ib phau ntawv txhais lus ntawm cov npe.
Kuj Paub, ua li cas koj iterate tshaj phau ntawv txhais lus hauv python? Muaj ob txoj hauv kev iterating los ntawm a Python phau ntawv txhais lus khoom. Ib qho yog txhawm rau nqa tus nqi cuam tshuam rau txhua tus yuam sij hauv keys() daim ntawv teev npe. Tseem muaj cov khoom () txoj kev ntawm phau ntawv txhais lus khoom uas xa rov qab cov npe ntawm tuples, txhua tuple muaj qhov tseem ceeb thiab tus nqi.
Yog li ntawd, koj yuav ua li cas xyuas seb tus yuam sij yog nyob rau hauv phau ntawv txhais lus python?
Kom yooj yim xyuas seb puas muaj tus yuam sij muaj nyob rau hauv ib Python phau ntawv txhais lus koj tuaj yeem siv tus neeg teb xov tooj los tshawb nrhiav los ntawm cov phau ntawv txhais lus zoo li no: tsiaj = {'cats': 1, 'dub': 2, 'ntses': 3} yog ' dev' hauv tsiaj: luam tawm ('Dog pom!') # dev pom!
Python phau ntawv txhais lus puas muaj ntau yam txiaj ntsig?
Hauv python , a phau ntawv txhais lus tau tsuas tuav ib leeg xwb tus nqi rau tus yuam sij muab. Txawm li cas los xij, yog tias koj siv hom ntaub ntawv muaj feem rau qhov ntawd tus nqi , koj yuav tsum tau txuag ntau tus nqi rau ib tus yuam sij. Kev xaiv 1: Siv ib tug tuple los sawv cev tus nqi ntawm tus yuam sij.

Ib tus yuam sij tseem ceeb puas tuaj yeem muaj ob tus yuam sij txawv teb chaws?
Nws yog qhov zoo kawg nkaus kom muaj ob kab ntawv tseem ceeb txawv teb chaws xa mus rau tib lub ntsiab lus tseem ceeb hauv ib lub rooj sib txawv vim tias txhua tus nqi tseem ceeb txawv teb chaws yuav siv cov ntaub ntawv sib txawv hauv cov lus hais
Dab tsi yog tus yuam sij ntiag tug thiab pej xeem tus yuam sij hauv Blockchain?
Thaum ib tug neeg xa koj cryptocoins hla Blockchain, lawv tau xa lawv mus rau qhov hashed version ntawm qhov hu ua "Public Key". Muaj lwm tus yuam sij uas zais ntawm lawv, uas yog hu ua "Private Key." Qhov Private Key no yog siv los muab Public Key
Koj txhais li cas los ntawm tus yuam sij ntiag tug thiab pej xeem tus yuam sij cryptography?
Nyob rau hauv pej xeem tus yuam sij cryptography, ob tus yuam sij yog siv, ib tug yuam sij yog siv rau encryption thiab thaum lwm yam yog siv rau decryption. 3. Nyob rau hauv private keycryptography, tus yuam sij yog khaws cia tsis pub leejtwg paub. Nyob rau hauv pej xeem tus yuam sij cryptography, ib qho ntawm ob tus yuam sij yog khaws cia tsis pub leejtwg paub
Ib tus yuam sij txawv teb chaws puas tuaj yeem siv lwm tus yuam sij txawv teb chaws?
1 Teb. Tus yuam sij txawv teb chaws tuaj yeem siv txhua qhov chaw uas txhais tau tias nws txawv. Yog hais tias qhov tshwj xeeb teb yog nws tus kheej txhais tau tias yog tus yuam sij txawv teb chaws, nws tsis txawv. Yog tias nws yog thaj chaw tshwj xeeb, nws kuj tuaj yeem yog lub hom phiaj ntawm lwm FK
Peb puas tuaj yeem muaj tib tus yuam sij hauv phau ntawv txhais lus python?
Teb. Tsis yog, txhua tus yuam sij hauv phau ntawv txhais lus yuav tsum muaj qhov tshwj xeeb. Koj tsis tuaj yeem muaj ob tus yuam sij nrog tus nqi tib yam. Kev sim siv tib tus yuam sij dua yuav cia li sau tus nqi yav dhau los khaws cia
