Essence of Python Library mu Data Science
M'chilengedwe chonse cha mapulogalamu, Python yadziwika bwino ngati chilankhulo chosankha pa sayansi ya data. Chifukwa chake ? Ma library ake amphamvu operekedwa kusanthula deta. Maphunziro a "Discover Python library for Data Science" pa OpenClassrooms zimakupatsirani kumizidwa mozama mu chilengedwe ichi.
Kuchokera pamagawo oyamba, mudzadziwitsidwa machitidwe abwino komanso chidziwitso chofunikira kuti muthe kusanthula kwanu ndi Python. Mupeza momwe malaibulale monga NumPy, Pandas, Matplotlib ndi Seaborn angasinthire njira yanu paza data. Zida izi zikuthandizani kuti mufufuze, kuwongolera ndikuwonera deta yanu mosayerekezeka komanso molondola.
Koma si zokhazo. Muphunziranso kufunikira kotsatira malamulo ena ofunikira pochita ndi kuchuluka kwa data. Mfundozi zidzakuthandizani kutsimikizira kudalirika ndi kufunikira kwa kusanthula kwanu.
Mwachidule, maphunzirowa ndi kuyitanidwa kuti mulowe m'dziko losangalatsa la sayansi ya data ndi Python. Kaya ndinu wongoyamba kumene kapena katswiri wofuna kukulitsa luso lanu, maphunzirowa akupatsani zida ndi njira zomwe mungapambane pamunda.
Dziwani Mphamvu za Ma Frames a Data kuti Mufufuze Bwino
Zikafika pakuwongolera ndi kusanthula deta yokhazikika, mafelemu a data ndiofunikira. Ndipo pakati pa zida zomwe zilipo kuti zigwire ntchito ndi ma data awa, Pandas imadziwika ngati mulingo wagolide mu chilengedwe cha Python.
Maphunziro a OpenClassrooms amakuwongolerani pang'onopang'ono popanga mafelemu anu oyamba a data ndi Pandas. Mitundu iwiriyi, yofanana ndi mindandanda imalola kusintha kosavuta kwa deta, kupereka kusanja, kusefa, ndi kugwirizanitsa magwiridwe antchito. Mupeza momwe mungasinthire mafelemu a datawa kuti mutenge zambiri, zosefera zenizeni komanso kuphatikiza ma data osiyanasiyana.
Koma Pandas sizongoyerekeza chabe. Laibulale imaperekanso zida zamphamvu zophatikiza deta. Kaya mukufuna kuchita ntchito zamagulu, kuwerengera ziwerengero zofotokozera kapena kuphatikiza ma dataset, Pandas wakuphimbani.
Kuti mukhale wogwira mtima mu sayansi ya data, sikokwanira kudziwa ma algorithms kapena njira zowunikira. Ndikofunikiranso kudziwa zida zomwe zimapangitsa kuti zitheke kukonzekera ndikukonza deta. Ndi Pandas, muli ndi wothandizira wamkulu kuti mukwaniritse zovuta zamakono zamakono zamakono.
Luso Lofotokozera Nkhani ndi Data yanu
Sayansi ya data singongotulutsa ndikuwongolera deta. Chimodzi mwa zinthu zochititsa chidwi kwambiri ndi luso lotha kuona chidziwitso ichi, kuchisintha kukhala zithunzithunzi zofotokozera nkhani. Apa ndipamene Matplotlib ndi Seaborn, malaibulale awiri odziwika kwambiri a Python, adalowa.
Maphunziro a OpenClassrooms amakufikitsani paulendo wodutsa zodabwitsa zakuwona kwa data ndi Python. Muphunzira kugwiritsa ntchito Matplotlib kupanga ma graph oyambira, monga ma chart a bar, histograms, ndi ziwembu zomwaza. Mtundu uliwonse wa tchati uli ndi tanthauzo lake komanso momwe amagwiritsidwira ntchito, ndipo mudzawongoleredwa ndi machitidwe abwino pazochitika zilizonse.
Koma zowonera sizimathera pamenepo. Seaborn, yomangidwa pa Matplotlib, imapereka zida zapamwamba zopangira zowonera zovuta komanso zowoneka bwino. Kaya ndi mapu otentha, ma fiddle chart, kapena magawo awiriawiri, Seaborn amapangitsa kuti ntchitoyi ikhale yosavuta komanso yachidziwitso.
