Kwihlabathi lokuguqulwa kwedatha kunye nohlalutyo, ukuphatha amaxabiso alahlekileyo ngumsebenzi obalulekileyo. Iipandas, ilayibrari yePython esetyenziswa ngokubanzi, ivumela ukuba silawule ngokufanelekileyo idatha engekhoyo. Enye indlela eqhelekileyo yokujongana namaxabiso angekhoyo ibandakanya ukusebenzisa izichazi-magama ukwenza imephu nokubuyisela ezi xabiso. Kweli nqaku, siza kuxubusha indlela yokunyusa amandla ePandas kunye nePython ukusebenzisa izichazi-magama zokutshintsha amaxabiso alahlekileyo kwidathasethi.
Python
Kuncinci ukwazisa kwiPython. Yaziwa kakuhle ngabo bonke abaphuhlisi.
Nantoni na oyifunayo inokwenziwa ngePython kwaye oku, kunye nokulula kunye nokulula, kuyenze enye yeelwimi zenkqubo yeenkwenkwezi namhlanje. Lulwimi oluchwethezwe ngamandla olujolise kwinto apho kubaluleke kakhulu ukugcina ukufundeka kwekhowudi.
Lulwimi lweenkwenkwezi kwisayensi yedatha, ukufundwa koomatshini, ukufunda nzulu, nayo yonke into enxulumene noko.
Kodwa usenokwakha usetyenziso lwewebhu, okanye nasiphi na esinye isixhobo onokucinga ngaso.
Kukho iivenkile zeencwadi zayo yonke into!!!
Kweli candelo sisombulula ezinye zeengxaki eziphambili umphuhlisi wePython ahlala ejongene nazo. Ngale ndlela indlela yokuba yi-ninja dev kwipython iqinisekisiwe.
Isonjululwe: uzishiya njani iintsuku ze-pandas datetime
Ifashoni kunye nenkqubo zinokubonakala ngathi ziihlabathi ezimbini ezahlukeneyo ngokupheleleyo, kodwa xa kufikwa kuhlalutyo lwedatha kunye noqikelelo lwemeko, zinokudibana kakuhle. Kweli nqaku, siza kuphonononga ingxaki eqhelekileyo yohlalutyo lwedatha kwishishini lefashoni: ukushiya iintsuku ezithile ukusuka kwidatha yedatha yepandas. Oku kunokuba luncedo ngakumbi xa uhlalutya iipateni, iintsingiselo, kunye nedatha yokuthengisa. Siza kuhamba ngesinyathelo-nge-nyathelo inkcazo yekhowudi, kwaye sixoxe ngamathala eencwadi ahlukeneyo kunye nemisebenzi eya kusinceda sifezekise injongo yethu.
Isonjululwe: iipanda zetafile ukuya kwi-postgresql
Ehlabathini lohlalutyo lwedatha kunye nokukhohlisa, enye yeelayibrari ezidumileyo zePython yi Iipandas. Ibonelela ngezixhobo ezahlukeneyo ezinamandla zokusebenza ngedatha ecwangcisiweyo, okwenza kube lula ukuyilawula, ukujonga ngamehlo kunye nokuhlalutya. Omnye wemisebenzi emininzi umhlalutyi wedatha anokuhlangabezana nayo kukungenisa idatha evela kwi-a CSV ifayile kwi a PostgreSQL idatabase. Kweli nqaku, siza kuxubusha indlela yokwenza lo msebenzi ngokufanelekileyo nangokufanelekileyo usebenzisa zombini Iipandas kwaye i Iifayile ithala leencwadi. Kwakhona siya kuphonononga imisebenzi eyahlukeneyo kunye namathala eencwadi abandakanyekayo kule nkqubo, sibonelela ngengqiqo ebanzi yesisombululo.
Isonjululwe: uthotho lweepandas zongeza igama kuyo yonke into ekuthotho
I-Pandas yilayibrari enamandla kwaye eguquguqukayo kwi-Python, esetyenziswa ngokuqhelekileyo ukukhohlisa idatha kunye nemisebenzi yokuhlalutya. Enye yezinto eziphambili kwiPandas yi uthotho into, eyenza i-dimensional enye, ileyibhile uluhlu. Kweli nqaku, siza kugxila kwingxaki ethile: ukongeza igama kuyo yonke into kwiPandas Series. Siza kuhamba ngesisombululo, sixoxe ngekhowudi yesinyathelo ngesinyathelo ukuqonda ukusebenza kwayo kwangaphakathi. Ukongeza, siza kuxoxa ngeelayibrari ezinxulumeneyo, imisebenzi, kunye nokubonelela ngemibono kwiingxaki ezifanayo.
Isonjululwe: yongeza iikholamu ezininzi kwi-dataframe ukuba azikho iipanda
I-Pandas yilayibrari ye-Python evulekileyo evulekileyo ebonelela ngokusebenza okuphezulu, izakhiwo zedatha ezilula ukuyisebenzisa, kunye nezixhobo zokuhlalutya idatha. Kuye kwaba yinto yokukhetha abaphuhlisi kunye nososayensi bedatha xa kufikwa kukuguqulwa kwedatha kunye nohlalutyo. Enye yezinto ezinamandla ezibonelelwa yiPandas idala kwaye iguqula i-dataframes. Kweli nqaku, siza kuphonononga inkqubo yokongeza iikholamu ezininzi kwi-dataframe ukuba azikho, usebenzisa ilayibrari yepandas. Siza kuhamba ngenyathelo ngenyathelo lenkcazo yekhowudi kwaye singene kwimisebenzi enxulumeneyo, amathala eencwadi, kunye neengxaki onokuthi udibane nazo endleleni.
Isonjululwe: faka iipanda zekholamu ezininzi
I-Pandas yilayibrari yePython enamandla kwaye eguquguqukayo esetyenziswa ngokubanzi ukukhohlisa kunye nohlalutyo lwedatha. Enye imfuno eqhelekileyo xa usebenza ngedatha kukufaka iikholamu ezininzi kwiDathaFrame. Kweli nqaku, siza kuphonononga inkqubo yokongeza iikholamu ezininzi kwiDathaFrame sisebenzisa ithala leencwadi lePanda, sixoxe ngekhowudi, kwaye singene nzulu kwimisebenzi enxulumeneyo, amathala eencwadi, kunye neekhonsepthi ezinokukunceda ube yingcali yePandas.
Isonjululwe: ukufumana inani lamaxabiso angekhoyo kwiipanda
I-Pandas yilayibrari esetyenziswa ngokubanzi evulekileyo yokukhohlisa idatha yePython. Ibonelela ngolwakhiwo lwedatha kunye nemisebenzi efunekayo ukulawula ngokufanelekileyo kunye nokuhlalutya iiseti zedatha ezinkulu. Enye ingxaki eqhelekileyo yedatha izazinzulu kunye nabahlalutyi badibana ngelixa usebenzisa i-pandas ukuphatha amaxabiso alahlekileyo kwidathasethi. Kweli nqaku, siza kuphonononga indlela yokubala inani lamaxabiso alahlekileyo kwi-pandas DataFrame usebenzisa iindlela ezahlukeneyo, iinkcazo zenyathelo ngenyathelo lekhowudi, kwaye sijonge nzulu kwezinye iilayibrari kunye nemisebenzi ebandakanyekayo ekusombululeni le ngxaki.
Isonjululwe: guqula isitampu sexesha sibe ziipandas zexesha
Kwihlabathi lanamhlanje, ukusebenza ngothotho lwedatha sisakhono esibalulekileyo kumphuhlisi. Omnye wemisebenzi eqhelekileyo kukuguqula isitampu sexesha kwixesha elithile, njengedatha yeveki okanye yenyanga. Lo msebenzi ubalulekile kuhlalutyo olwahlukeneyo, njengokufunda iintsingiselo kunye neepateni kwidatha. Kweli nqaku, siza kuphonononga indlela yokuguqula isitampu sexesha kwixesha kwidatha-seti yedatha usebenzisa ithala leencwadi lePython elinamandla, iPandas. Siza kuphinda singene nzulu kwikhowudi, siphonononge amathala eencwadi kunye nemisebenzi ebandakanyekayo kwinkqubo, kwaye siqonde ukubaluleka kwayo ekusombululeni le ngxaki.
I-Pandas i-open-source-source analysis data kunye nelayibrari yokukhwabanisa, ebonelela ngemisebenzi eguquguqukayo kunye nephezulu yokusebenza kunye nedatha yexesha. Yenza umsebenzi wethu ube lula, uchanekile kwaye usebenze kakuhle.
Isonjululwe: hluza zonke iikholamu kwiipanda
Kwihlabathi lohlalutyo lwedatha, ukuphatha iiseti zedatha enkulu kunokuba ngumsebenzi onzima. Enye yeendawo ezibalulekileyo zale nkqubo kukucoca idatha ukufumana ulwazi olufanelekileyo. Xa kuziwa kwiPython, ithala leencwadi elinamandla pandas uya kusinceda. Kweli nqaku, siza kuxubusha indlela yokucoca yonke imiqolo kwipandas DataFrame. Siza kuhamba ngesinyathelo-nge-nyathelo inkcazo yekhowudi kwaye sinikeze ukuqonda okunzulu kwamathala eencwadi kunye nemisebenzi engasetyenziselwa iingxaki ezifanayo.
