Isandi esiphucukileyo? Luluhlu lwePython lokuqonda kwakho. Olu phawu lusebenza kakhulu ludibanisa ukuyilwa koluhlu kumgca omnye wekhowudi. Yindlela eyenziwe lula eyenza isantya kunye nokusebenza.
Ukuqonda koluhlu kubandakanya ukuqonda amacandelo oluhlu kunye nokwenza uluhlu olutsha koluqobo. Idibanisa izinto zemephu kunye nokucoca ukwenza uluhlu olutsha ngokusekelwe kuluhlu olukhoyo, kunye nemeko eyongezelelweyo. Amacandelo ayo aphambili sisiBoniso sePhumo, ulandelelwano lwegalelo, kunye nesiQalo esiKhethekileyo.
new_list = [expression for member in iterable]
Ngaphambi kokuba singene nzulu ekusebenzeni koludwe lokuqonda, makhe sicacise amanye amagama:
Ukubonakaliswa kwemveliso:
Oku kufana nenxalenye esebenzayo yohlu lokuqonda. Igqiba ukuba zeziphi izinto eziya kuba yinxalenye yoluhlu olutsha. Ingayiyo nantoni na ukusuka kwimisebenzi yezibalo (njengamanani e-squaring) ukuya kufomato lomtya kunye nokunye.
Ulandelelwano lwegalelo:
Ulandelelwano lwegalelo lisivumela ukuba sichaze uluhlu okanye uluhlu apho sifuna ukuphinda-phinda.
Isibikezelo Esinokuzikhethela:
Eli candelo lisivumela ukuba sisebenzise imeko kulandelelwano lwegalelo - njengesihluzo. Umqathango unokuhluza izinto ezisekelwe kwiikhrayitheriya ezithile.
Qwalasela umzekelo apho sifuna ukuphinda-phinda inani ngalinye kuluhlu. Ngaphandle koluhlu lokuqonda, kuya kufuneka sisebenzise i-loop:
numbers = [1, 2, 3, 4, 5]
squared = []
for num in numbers:
squared.append(num ** 2)
print(squared)
Kodwa ngokuqondwa koluhlu, sinokubhala ngokulula oku:
numbers = [1, 2, 3, 4, 5] squared = [num ** 2 for num in numbers] print(squared)
Ngoku, qwalasela umzekelo apho sifuna kuphela ukuphindaphinda amanani amakhulu kuno-2:
numbers = [1, 2, 3, 4, 5] squared = [num ** 2 for num in numbers if num > 2] print(squared)
Ukuyifaka
Ukuqonda koluhlu lwePython kubonelela ngesisombululo esifutshane ngokugqibeleleyo sokwenza uluhlu. Iyakhawuleza kwaye ifundeka ngakumbi (xa sele uyiqhelile) kunelophu zemveli. Ngentetho yemveliso, ulandelelwano lwegalelo, kunye nesivisa esikhethiweyo, ungenza imisebenzi enamandla nesebenzayo kumgca omnye wekhowudi. Ukuqonda koluhlu lwePython bubungqina bokuba, ekubhaleni ikhowudi, akufane kwenzeke ukuba mfutshane kunye nokusebenza kakuhle kungahambi ngesandla.
Nceda uqinisekise ukuba unciphisa iibhloko zekhowudi yePython nge, phawula uluhlu nge
- , kwaye usebenzise i ithegi yamagama angundoqo ukuhlangabezana ne-SEO kunye neemfuno zokufunda-ubuhlobo. Akuyomfuneko ukuba uleyibhelishe ngokucacileyo “intshayelelo” okanye “isiphelo”, kwaye qiniseka ukuba wongeza ithegi emva komhlathi wokuqala. Ikhowudi yolonwabo!
