Undoqo wamathala eencwadi ePython kwiSayensi yeDatha
Kwihlabathi elikhulu lenkqubo, iPython iye yagqama njengolwimi olukhethwayo kwisayensi yedatha. Isizathu ? Iilayibrari zayo ezinamandla ezinikezelwe kuhlalutyo lwedatha. Ikhosi "Fumana iilayibrari zePython zeSayensi yeDatha" kwiiClassrooms ezivulekileyo ikunika untywiliselo olunzulu kule ecosystem.
Ukusuka kwiimodyuli zokuqala, uya kwaziswa ngeendlela ezilungileyo kunye nolwazi olusisiseko ukwenza uhlalutyo lwakho ngePython. Uya kufumanisa ukuba amathala eencwadi anjengeNumPy, iPandas, iMatplotlib kunye neSeaborn anokutshintsha njani indlela yakho yedatha. Ezi zixhobo ziya kukuvumela ukuba uphonononge, ulawule kwaye ubone ngeso lengqondo idatha yakho ngokusebenza okungenakulinganiswa kunye nokuchaneka.
Kodwa akuphelelanga apho. Uya kufunda kwakhona ukubaluleka kokulandela eminye imithetho esisiseko xa ujongana nezixa ezikhulu zedatha. Le migaqo iya kukunceda uqinisekise ukuthembeka kunye nokufaneleka kohlalutyo lwakho.
Ngokufutshane, le khosi sisimemo sokuntywila kwihlabathi elinomdla lesayensi yedatha ngePython. Nokuba ungumqali onomdla wokwazi okanye unobuchule obujonge ukucokisa izakhono zakho, le khosi iya kukubonelela ngezixhobo kunye nobuchule obufunekayo ukuze ugqwese ebaleni.
Fumanisa aMandla eZisakhelo zeDatha zoHlalutyo olusebenzayo
Xa kufikwa ekusebenzisaneni nasekuhlalutyeni idatha eyakhiweyo, izakhelo zedatha zibalulekile. Kwaye phakathi kwezixhobo ezikhoyo zokusebenza ngezi zakhiwo zedatha, iPandas ivelele njengomgangatho wegolide kwi-ecosystem yePython.
Ikhosi ye-OpenClassrooms iyakukhokela inyathelo ngenyathelo ngokwenza isakhelo sedatha yakho yokuqala ngeePanda. Ezi zakhiwo zine-dimensional, uluhlu-ezifana nolwakhiwo luvumela ukuguqulwa lula kwedatha, ukubonelela ngokuhlela, ukuhluza, kunye nokusebenza kokuhlanganiswa. Uya kufumanisa ukuba uzisebenzisa njani ezi zakhelo zedatha ukukhupha ulwazi olufanelekileyo, ukucoca idatha ethile kunye nokudibanisa imithombo eyahlukeneyo yedatha.
Kodwa iPandas ingaphezulu nje kokukhohlisa. Ithala leencwadi likwabonelela ngezixhobo ezinamandla zokudibanisa idatha. Nokuba ufuna ukwenza imisebenzi yeqela, ubale iinkcukacha-manani ezichazayo okanye udibanise iiseti zedatha, iPandas ikugqumile.
Ukuphumelela kwisayensi yedatha, akwanele ukwazi i-algorithms okanye ubuchule bokuhlalutya. Kubaluleke ngokufanayo ukukwazi kakuhle izixhobo ezenza ukuba kube lula ukulungiselela kunye nokwakhiwa kwedatha. NgePandas, unomhlobo omkhulu wokuhlangabezana nemingeni yesayensi yedatha yanamhlanje.
UbuGcisa bokuBalisa amabali ngeDatha yakho
Inzululwazi yedatha ayikho malunga nokukhupha kunye nokukhohlisa idatha. Enye yezona nkalo zinomtsalane kukukwazi ukwenza umfanekiso-ngqondweni wolu lwazi, luluguqule lube yimizobo ebonisa ibali. Kulapho uMatplotlib kunye noSeaborn, ezimbini zezona thala zeencwadi zokubonwa zidumileyo zePython, zeza kudlala.
Ikhosi ye-OpenClassrooms ikuthatha kuhambo ngokusebenzisa imimangaliso yokubonwa kwedatha ngePython. Uya kufunda ukusebenzisa iMatplotlib ukwenza iitshathi ezisisiseko, ezinjengeetshathi zebha, iihistograms, kunye neziza zokuchithachitha. Uhlobo ngalunye lwetshathi lunentsingiselo yalo kunye nomxholo wokusetyenziswa, kwaye uya kukhokelwa ngezona ndlela zokuziphatha kwimeko nganye.
Kodwa ukubonwa akupheli apho. I-Seaborn, eyakhelwe kwi-Matplotlib, ibonelela ngeempawu eziphambili zokudala ukubonwa okuntsokothileyo kunye nokwaneliseka ngobuhle. Nokuba ziimephu zobushushu, iiploti zevayolin, okanye izibini zeploti, i-Seaborn iyenza ibelula kwaye ibelula.
