Emhlabeni wezinhlelo, iPython isiwulimi oludumile olwaziwa ngokusebenziseka kalula, ukufundeka, nokuguquguquka. Phakathi kwemitapo yolwazi yayo eminingi, iNumPy igqama njengelinye lamathuluzi anamandla okuphatha idatha yezinombolo, enezinhlelo eziningi zokusebenza emikhakheni eyahlukene, okuhlanganisa nemfashini. Kulesi sihloko, sizocubungula umsebenzi we-NumPy Shape, sidingida i-syntax yayo futhi sinikeze isisombululo esisebenzayo enkingeni ebandakanya ukuhlaziywa kwezitayela zemfashini. Njengoba siqhubeka, sizophinde sihlole imitapo yolwazi ehlobene nemisebenzi. Ngakho, ake siqale!
I-NumPy
Kuxazululiwe: ikholomu ye-python numpy susa
Kulesi sihloko, sizoxoxa ngolimi lohlelo lwe-Python, sigxile kakhulu kumtapo wezincwadi i-NumPy nokuthi ungayisusa kanjani ikholomu usebenzisa le labhulali. I-Python iwulimi lokuhlela oluguquguqukayo olusetshenziswa kabanzi ngezinhloso ezahlukahlukene, kufaka phakathi ukuthuthukiswa kwewebhu, ukuhlaziya idatha, ubuhlakani bokwenziwa nokunye. Enye yezingxenye ezibalulekile zokuthandwa kwePython imitapo yolwazi yayo eminingi, eyenza inqubo yokufaka amakhodi isebenze kahle futhi kube lula ukuyiphatha. I-NumPy iwumtapo wolwazi onjalo, oklanyelwe ngokukhethekile ukusebenza ngamaqoqo amakhulu, anezinhlangothi eziningi kanye namatrices wedatha yezinombolo. Emkhakheni wokukhohlisa idatha, kubalulekile ukwazi ukuthi uwasusa kanjani amakholomu ohlwini, njengoba lesi kuyisinyathelo esivamile sokucubungula ngaphambilini ekuhambeni komsebenzi okuningi.
Kuxazululiwe: Python NumPy ascontiguousarray Function Isibonelo Tuple kuhlelo
I-Python NumPy iwumtapo wezincwadi odumile owakhiwe eduze kwento ye-NumPy array, okungenye indlela enamandla nephumelelayo ohlwini olujwayelekile lwePython. Kulesi sihloko, sizoxoxa ngomunye wemisebenzi ewusizo etholakala kulabhulali ye-NumPy, i i-ascontiguousarray umsebenzi. Lo msebenzi uzuzisa kakhulu uma usebenza nezinhlaka mayelana nokuguqula amalungu afanayo abe amalungu afanayo ahlangene kanye nokusingatha izakhiwo zedatha ezifana nama-tuples. Injongo eyinhloko yomsebenzi we-ascontiguousarray iwukuqinisekisa ukuthi amalungu afanayo anikeziwe agcinwe kubhulokhi yememori ehlangene.
Kuxazululiwe: I-NumPy packbits Ikhodi Ipakishwe amalungu afana ne-eksisi 1
I-NumPy iwumtapo wezincwadi onamandla ku-Python osetshenziswa kabanzi ekubalweni kwezinombolo kuhlu lwezakhiwo zedatha ye-matrix. Omunye wemisebenzi eminingi ewunikezayo ngu amaphakethe, okukuvumela ukuthi ufake ikhodi kanambambili ngendlela efanele eksisi eshiwo. Kulesi sihloko, sizohlola ukusetshenziswa kwamaphakethe we-NumPy ku-axis 1, futhi sixoxe ngamasu kanye nokusetshenziswa kwayo. Njengoba siqhubeka, sizophinde sihlole imitapo yolwazi ehlobene nokusebenza kwayo.
Kuxazululiwe: numpy collapse ubukhulu bokugcina
Eminyakeni yamuva nje, ukusetshenziswa kwePython emikhakheni ehlukahlukene kuye kwanda kakhulu, ikakhulukazi emkhakheni wokukhohlisa idatha kanye nekhompyutha yesayensi. Omunye wemitapo yolwazi esetshenziswa kakhulu kule misebenzi iNumPy. I-NumPy iwumtapo wolwazi onamandla futhi oguquguqukayo osetshenziswa kakhulu ekusebenzeni ngamaqoqo amakhulu, ama-multidimensional kanye namatrices, phakathi kweminye imisebenzi yezibalo. Umsebenzi owodwa ovamile ekusebenzeni nalezi zakhiwo zedatha isidingo sokugoqa noma ukwehlisa ubukhulu bokugcina belungu elifanayo. Kulesi sihloko, sizohlola lesi sihloko ngokuningiliziwe, siqale ngesingeniso senkinga, silandelwe yisixazululo, kanye nencazelo yesinyathelo ngesinyathelo sekhodi. Okokugcina, sizocubungula ezinye izihloko ezihlobene namalabhulali okungenzeka kube nentshisekelo kuwo.
Kuxazululiwe: Bala i-Jordan uhlobo oluvamile lwe-matrix kuPython %2F NumPy
I-matrix computation iyindlela esetshenziswa kakhulu emikhakheni ehlukahlukene efana nesayensi, ubunjiniyela, neminye. Enye yezindlela ezibalulekile ekubhekaneni nomatikuletsheni ukuthola uhlobo olujwayelekile lwaseJordani lwe-matrix enikeziwe. Kulesi sihloko, sizocubungula inqubo yokwenza ikhompuyutha yohlobo olujwayelekile lwaseJordani lwe-matrix kusetshenziswa iPython neNumPy, umtapo wezincwadi onamandla wokubala izinombolo. Sizohamba ngesixazululo ngendlela enemininingwane, yesinyathelo nesinyathelo, sichaza ikhodi kanye nezindlela ezihilelekile. Ngaphezu kwalokho, sizoxoxa ngemitapo yolwazi ehlobene nemisebenzi engasiza ekuxazululeni izinkinga ezifanayo.
Kuxazululiwe: okufakiwe okungahleliwe okungaphindwaphindwa
Ezweni lanamuhla lokukhohlisa nokuhlaziya idatha, inkinga eyodwa evamile ephakamayo ukukhiqiza okungaphindi okungahleliwe okufakiwe kusetshenziswa umtapo wezincwadi wePython odume kakhulu i-NumPy. Lesi sihloko sihlose ukuhlinzeka ngesixazululo esibanzi sale nkinga, sijule ekusebenzeni kwangaphakathi kwekhodi kanye nokuhlola imitapo yolwazi nemisebenzi efanele.
I-NumPy iwumtapo wezincwadi onamandla osenza sikwazi ukwenza imisebenzi ehlukahlukene yezibalo nezibalo kuma-multi-dimensional array kanye namatrices. Esinye sezici ezibalulekile zokuhlaziya idatha nokufunda komshini ukukhiqiza izinombolo ezingahleliwe, ezingafinyelelwa kusetshenziswa imojuli engahleliwe ye-NumPy. Kwezinye izimo, singase sidinge lokhu okufakiwe okungahleliwe ukuze kuhluke futhi kungaphindi. Ake sihlole ukuthi singakwenza kanjani lokhu sisebenzisa i-NumPy isinyathelo ngesinyathelo.
Kuxazululiwe: numpy kanye no-opharetha
I-NumPy futhi Opharetha ziyimitapo yolwazi emibili ebaluleke kakhulu emhlabeni wezinhlelo ze-Python, ikakhulukazi ngaphakathi kwendawo yokukhohlisa idatha nokusebenza kwezibalo. Kulesi sihloko, sizocubungula amandla alemitapo yolwazi yomibili futhi sixoxe ngokusetshenziswa kwayo ekuxazululeni izinkinga eziyinkimbinkimbi ngendlela elula nephumelelayo. Ukuze siqonde kangcono, sizoqala ngesingeniso se-NumPy kanye no-opharetha, silandelwe yisixazululo sesinyathelo ngesinyathelo senkinga ethile sisebenzisa lemitapo yolwazi. Ngaphezu kwalokho, sizohlola imisebenzi engeziwe efanele kanye namasu athuthukisa amakhono ethu okusebenza ngama-arrays kanye nokusebenza kwezibalo kuPython.
Ixazululiwe: I-Python NumPy ihlukanisa i-Syntax Yomsebenzi
Isingeniso
I-Python iwulimi lokuhlela oluguquguqukayo futhi olusetshenziswa kabanzi emikhakheni eyahlukene, okuhlanganisa ukuhlaziywa kwedatha, ubuhlakani bokwenziwa, nokuthuthukiswa kwewebhu. Enye yemitapo yolwazi ebalulekile yokuphatha idatha yezinga elikhulu kuPython ngu I-NumPy. I-NumPy ihlinzeka ngento enamandla ye-N-dimensional array, esenza sikwazi ukwenza imisebenzi yezibalo eyinkimbinkimbi kalula. Omunye wemisebenzi ebalulekile ekuhlaziyeni idatha yi- umsebenzi wokuhlukanisa, esetshenziselwa ukuhlukanisa idatha ibe izingxenye ezincane ukuze kuhlaziywe okwengeziwe. Kulesi sihloko, sizongena ku-syntax nasekusetshenzisweni komsebenzi wokuhlukanisa we-NumPy ngokuhlinzeka ngesixazululo esisebenzayo, incazelo yesinyathelo nesinyathelo, nokuxoxa ngemitapo yolwazi nemisebenzi ehlobene.
