A duniyar yau, shirye-shirye wani fasaha ne mai mahimmanci, kuma Python yana daya daga cikin shahararrun yarukan shirye-shirye saboda sauki da kuma dacewa. A matsayina na kwararre a Python kuma mai sha'awar kayyayaki, Ina jin daษin nutsewa cikin hanyoyin musamman a Python, musamman dangane da jeri. A cikin wannan labarin, za mu bincika matsala da ke da alaฦa da magudi, tattauna mafita, da kuma ba da bayanin mataki-mataki na lambar. Bugu da ฦari, za mu shiga cikin ษakunan karatu da ayyuka masu alaฦa da matsalar don ฦara fahimtar iyawar Python.
Fahimtar Matsala
A cikin duniyar salon, yanayin yanayi da salo suna canzawa da sauri. A sakamakon haka, sarrafawa da tsara manyan tarin kayan ado yana da mahimmanci ga masu zanen kaya da gidajen kayan ado. Za mu iya amfani da Python don ฦirฦirar shirin da zai ba mu damar sarrafa jerin abubuwan kayan sawa da kyau. Babban burinmu shine ฦirฦirar nau'in jeri-kamar al'ada tare da hanyoyi na musamman waษanda ke da ikon sarrafa ayyuka daban-daban kamar rarrabewa ta atomatik ta launuka, salo, ko masu ฦira.
Domin cim ma wannan aikin, muna buฦatar fahimta da amfani da Python's hanyoyin da aka gina a ciki, hanyoyin sihiri, kuma wasu dakunan karatu na waje masu dacewa wanda zai iya taimakawa inganta shirin mu.
Magani: ฦirฦirar Class List na Musamman
Don magance wannan matsala, za mu iya ฦirฦirar ajin Python na al'ada da ake kira List of Fashion, wanda ke aiki daidai da nau'in lissafin da aka gina. Wannan ajin zai sami hanyoyi na musamman waษanda ke ษaukar takamaiman buฦatu da buฦatu don sarrafa kayan kayan kwalliya, kamar rarraba abubuwa ta launi, salo, ko ฦira.
Kafin nutsewa cikin lambar, yana da mahimmanci a fahimci Python's hanyoyin sihiri. Hanyoyin sihiri hanyoyi ne na musamman a cikin azuzuwan Python waษanda ke da ma'ana sau biyu a farkon da ฦarshen sunayensu, kamar `__init__` da `__str__`. Waษannan hanyoyin suna ba mu damar tsara halayen ajin mu.
Da farko, bari mu ฦirฦiri ajin FashionList kuma mu fara aiwatar da hanyoyin musamman.
class FashionList: def __init__(self): self.items = [] def __str__(self): return f'FashionList: {str(self.items)}' def __len__(self): return len(self.items) def __getitem__(self, index): return self.items[index] def append(self, item): self.items.append(item) # More methods will be added here
A cikin lambar da ke sama, mun bayyana mai sauฦi FashionList class tare da hanyoyin sihiri masu zuwa:
- `__init__`: Yana fara lissafin fanko mai suna 'abubuwa' lokacin da aka ฦirฦiri wani abu na FashionList.

Mun kuma ฦara hanyar 'append' mai sauฦi don ฦara sabbin abubuwa zuwa lissafin.
Aiwatar da Hanyoyi Na Musamman
Yanzu da muke da ainihin ajin FashionList, za mu iya ฦara hanyoyin rarrabuwa na al'ada don ษaukar takamaiman buฦatu don sarrafa kayan kwalliya. Don wannan dalili, za mu yi amfani da ginanniyar aikin ''jere'' na Python, wanda ke karษar maษalli mai mahimmanci don tsara rarrabuwa. Za mu kuma yi amfani da laburare kala-kala, wanda ke taimakawa rarrabuwar launuka ta hanyar da mutum zai iya karantawa, da kuma enum library ga style enums.
