An warware: Fahimtar Lissafi

Sauti na sophisticated? Wannan shine fahimtar lissafin Python a gare ku. Wannan fasalin ingantaccen inganci yana ƙarfafa ƙirƙirar jeri a cikin layi ɗaya na lamba. Hanya ce mai sauƙi wacce ke daidaita saurin gudu da aiki.

Fahimtar lissafin ya ƙunshi fahimtar abubuwan da ke cikin jeri da ƙirƙirar sabon jeri daga ainihin ɗaya. Yana haɗa abubuwa na taswira da tacewa don ƙirƙirar sabon jeri bisa jerin da ke akwai, tare da ƙarin yanayin. Babban abubuwan da ke tattare da shi shine Bayanin Fitarwa, Jerin Input, da Predicate Na zaɓi.

new_list = [expression for member in iterable]

Kafin mu zurfafa zurfafa cikin ayyukan fahimtar lissafin, bari mu share wasu sharuɗɗan:

Bayanin Fitarwa:

Wannan yana kama da sashin aiki na fahimtar lissafin. Yana yanke shawarar abubuwan da za su kasance cikin sabon jeri. Yana iya zama wani abu daga ayyukan lissafi (kamar lambobi masu ƙima) zuwa tsara kirtani da ƙari.

Jerin shigarwa:

Jerin shigarwa yana ba mu damar ayyana jeri ko kewayon da muke son maimaitawa.

Ƙididdigar Zaɓuɓɓuka:

Wannan ɓangaren yana ba mu damar amfani da yanayi zuwa jerin shigarwar - kamar tacewa. Yanayin na iya tace abubuwa bisa wasu sharudda.

Yi la'akari da misali inda muke so mu daidaita kowace lamba a cikin jeri. Ba tare da fahimtar lissafin ba, dole ne mu yi amfani da madauki don madauki:

numbers = [1, 2, 3, 4, 5]
squared = []

for num in numbers:
    squared.append(num ** 2)

print(squared)

Amma tare da fahimtar lissafin, zamu iya rubuta wannan cikin sauƙi:

numbers = [1, 2, 3, 4, 5]
squared = [num ** 2 for num in numbers]

print(squared)

Yanzu, yi la'akari da misali inda kawai muke so mu daidaita lambobin da suka fi 2:

numbers = [1, 2, 3, 4, 5]
squared = [num ** 2 for num in numbers if num > 2]

print(squared)

Kashe shi

Fahimtar lissafin Python yana ba da ƙayyadaddun ƙayyadaddun bayani don ƙirƙirar jeri. Yana da sauri kuma ana iya karantawa (da zarar kun saba dashi) fiye da madaukai na gargajiya. Tare da bayanin fitarwa, jerin shigarwar, da predicate na zaɓi, zaku iya aiwatar da ayyuka masu ƙarfi da inganci a cikin layi ɗaya na lamba. Fahimtar lissafin Python hujja ce cewa, a cikin coding, ba safai ake yin taƙaice da inganci ba sa tafiya hannu da hannu.

Da fatan za a tabbatar da iyakance katangar lambar Python tare da , yi alama da jerin sunayen

• , kuma amfani da tag don manyan kalmomi don saduwa da SEO da buƙatun abokantaka na masu karatu. Ba kwa buƙatar yi wa lakabin “gabatarwa” ko “kammalawa” a sarari, kuma ku tabbata kun ƙara tag bayan sakin layi na farko. Happy codeing!
