Yakagadziriswa: kugadzirisa faira kakawanda mupandas
Kugadziridza faira kakawanda muPandas chinhu chakakosha paunenge uchishanda nemaseti makuru mumunda wekuongorora data, manipulation data, uye kuchenesa data. Pandas iraibhurari yePython inoshandiswa zvakanyanya inopa nyore-kushandisa-data zvimiro uye maturusi ekuongorora data ayo anobvumira vashandisi kubata nemafomati akasiyana efaira akadai seCSV, Excel, uye SQL dhatabhesi.
Dambudziko guru ratichatarisa pakugadzirisa munyaya ino nderekugadzirisa faira kakawanda uchishandisa raibhurari yePandas muPython. Izvi zvinosanganisira kuverenga iyo data, kuita shanduko dzinodikanwa kana shanduko, uyezve kunyora iyo data kufaira. Isu tichaongorora chikamu chimwe nechimwe chemaitiro, tichitsanangura kodhi inosanganisirwa, uye kukurukura akati wandei maraibhurari uye mabasa ane chekuita nedambudziko iri.

Yakagadziriswa: wedzera akawanda makoramu kune dataframe kana isipo pandas
Pandas iraibhurari yakavhurika-sosi yePython inopa kushanda kwepamusoro, nyore-kushandisa-data zvimiro, uye maturusi ekuongorora data. Yakave sarudzo yekuenda kune vanogadzira uye data masayendisiti kana zvasvika pakubata data uye kuongorora. Chimwe chezvinhu zvine simba zvinopihwa nePandas kugadzira nekugadzirisa dataframes. Muchikamu chino, tichaongorora maitiro ekuwedzera akawanda makoramu kune dataframe kana isipo, tichishandisa pandas raibhurari. Isu tichafamba nenhanho-ne-nhanho tsananguro yekodhi uye kunyura mumabasa ane hukama, maraibhurari, uye matambudziko aungasangana nawo munzira.
