Inzwi rakaomarara? Ndiyo Python rondedzero kunzwisisa kwauri. Ichi chinoshanda zvakanyanya chinokonesa kusikwa kwezvinyorwa kuita mutsara mumwe wekodhi. Inzira yakareruka inorerutsa kukurumidza uye kuita.
Kunzwisisa rondedzero kunosanganisira kunzwisisa zvikamu zverunyorwa uye kugadzira runyoro rutsva kubva kune rwekutanga. Inosanganisa zvinhu zvemepu uye kusefa kugadzira runyorwa rutsva rwakavakirwa pane iripo runyorwa, ine yakawedzerwa mamiriro. Zvikamu zvaro zvikuru ndezveKuburitsa Kuburitsa, Kutevedzana Kwekupinda, uye Optional Predicate.
new_list = [expression for member in iterable]
Tisati tanyura mukushanda kwekunzwisisa kwerondedzero, ngatijekese mamwe mazwi:
Output Expression:
Izvi zvakafanana nechikamu chinoshanda chekunzwisisa runyorwa. Inosarudza kuti ndezvipi zvinhu zvichave chikamu cherunyorwa rutsva. Inogona kunge iri chero chinhu kubva kumabasa emasvomhu (senge nhamba dze squaring) kuenda kune tambo fomati nezvimwe.
Input Sequence:
Kutevedzana kwekupinza kunoita kuti titsanangure rondedzero kana mutsara watinoda kudzokorora.
Optional Predicate:
Ichi chikamu chinoita kuti tishandise mamiriro kune yekuteedzera kutevedzana - sefa. Mamiriro acho anogona kusefa zvinhu zvichibva pane mamwe maitiro.
Funga nezvemuenzaniso watinoda kupeta nhamba imwe neimwe muhurongwa. Pasina rondedzero yenzwisiso, isu taizofanira kushandisa for loop:
numbers = [1, 2, 3, 4, 5]
squared = []
for num in numbers:
squared.append(num ** 2)
print(squared)
Asi nekunzwisisa runyoro, tinogona kunyora izvi zviri nyore:
numbers = [1, 2, 3, 4, 5] squared = [num ** 2 for num in numbers] print(squared)
Zvino, funga muenzaniso apo isu tinongoda kukwereta nhamba dzakakura kupfuura 2:
numbers = [1, 2, 3, 4, 5] squared = [num ** 2 for num in numbers if num > 2] print(squared)
Kuuputira iyo
Python rondedzero kunzwisiswa inopa inoyevedza yakapfupika mhinduro yekugadzira rondedzero. Inokurumidza uye inoverengeka (kana iwe uchinge wajairana nayo) kupfuura zvishwe zvechinyakare. Nekubuda kwekutaura, kutevedzana kwekuisa, uye sarudzo ye predicate, unogona kuita zvine simba uye zvinobudirira mashandiro mumutsara mumwe wekodhi. Python runyorwa runyoro humbowo hwekuti, mukunyora kodhi, kashoma kuita hutsanana uye kugona hazvienderane.
Ndokumbira utarise mabhuroko ePython kodhi ne, maka rondedzero ne
- , uye shandisa tag yemashoko makuru kusangana neSEO uye muverengi-ushamwari zvinodiwa. Haufanire kunyora zvakajeka "nhanganyaya" kana "mhedziso", uye iva nechokwadi chekuwedzera tag mushure mendima yekutanga. Happy coding!
