An warware: yadda ake yin lissafin 2d na jerin kirtani

A duniyar shirye-shirye, masu haษ“akawa galibi suna fuskantar matsaloli da yawa don magance su. ฦŠayan irin wannan matsalar gama gari a Python shine ฦ™irฦ™irar jerin 2D daga jerin kirtani. A cikin wannan labarin, za mu tattauna tsari, bayani, da bayanin mataki-mataki na lambar don magance wannan batu mai ban sha'awa. Bugu da ฦ™ari, za mu bincika dakunan karatu masu alaฦ™a da ayyuka waษ—anda za su iya haษ“aka fahimtar ku da dacewa yayin aiki tare da Python.

ฦ˜irฦ™irar jerin 2D daga jerin kirtani aiki ne na gama gari a Python. Wannan gaskiya ne musamman lokacin sarrafawa da nazarin bayanai daga tushe daban-daban kamar fayilolin rubutu, bayanan bayanai, ko ma hanyoyin yanar gizo. Waษ—annan tsarin bayanan suna da mahimmanci don adanawa da sarrafa bayanai cikin tsari da tsari, wanda ke da mahimmanci yayin aiki tare da manyan bayanan bayanai a fagen ilimin kimiyyar bayanai, koyon injin, da sauran fagage da yawa.

Don cimma wannan, za mu yi amfani da sauฦ™i don madauki da madauki lissafin fahimta fasaha a Python. Ga maganin matsalar:

input_list = ["Hello", "World", "Python"]
two_d_list = [[char for char in string] for string in input_list]
print(two_d_list)

Bari mu rushe lambar mataki-mataki:

1. Input_list m ya ฦ™unshi jerin igiyoyin mu.
2. The two_d_list m ya ฦ™unshi fahimtar lissafin gida, wanda ke canza jerin kirtani zuwa jerin 2D.
3. Ga kowane kirtani a cikin input_list, lissafin ciki yana aiwatar da haruffa ษ—aya bayan ษ—aya.
4. Ana ฦ™ara waษ—annan haruffa guda ษ—aya zuwa lissafin wucin gadi.
5. A ci gaba da tsari ga kowane kirtani a input_list.
6. A ฦ™arshe, print() yana nuna two_d_list, wanda yanzu shine 2D array.

Fitowar lambar zai kasance:

โ€œโ€œ
['H', 'e', โ€‹โ€‹'l', 'l', 'o'], ['W', 'o', 'r', 'l', 'd'], ['P', 'y', 't', 'h', 'o', 'n']]
โ€œโ€œ

Wannan hanya ce mai sauฦ™i amma mai ฦ™arfi don sauya jerin kirtani zuwa jerin 2D ta amfani da iyawar Python.

Fahimtar jerin Python

Lissafin fahimta fasali ne na musamman a cikin Python, yana ba ku damar ฦ™irฦ™irar jerin abubuwa cikin sauri da taฦ™aitaccen bayani. Waษ—annan ba wai kawai adana lokaci bane amma kuma suna ba da kyakkyawar hanya mai inganci ta ฦ™irฦ™irar lissafin tare da ฦ™aramin ฦ™oฦ™ari.

Asalin tsarin fahimtar lissafin shine kamar haka:

โ€œโ€œ
[bayani don abu a cikin mai yiwuwa idan yanayin]
โ€œโ€œ

Wannan ฦ™aramin lambar tana fassara zuwa:

1. ฦ˜imar ฦ™ayyadaddun furci na kowane abu a cikin mai iya sarrafa shi, kamar jeri ko kewayo.
2. Idan an bayar da zaษ“in 'idan yanayin', kawai haษ—a abu a cikin jerin sakamakon idan yanayin ya kimanta zuwa Gaskiya.

Ana ba da shawarar fahimtar lissafin don iya karantawa da gajeriyar su, da kuma ingantaccen aikinsu idan aka kwatanta da yin amfani da na gargajiya don madaukai.

Ginbun ษ—akunan karatu na Python

Python yana ba da ษ—akunan ษ—akunan karatu da yawa waษ—anda za su iya taimakawa tare da ayyuka daban-daban na shirye-shirye. Waษ—annan ษ—akunan karatu wani sashe ne mai mahimmanci na yanayin yanayin Python kuma suna ba da ฦ™arfi, abin dogaro, da ingantattun ayyuka don masu haษ“akawa suyi amfani da su.

Don matsalarmu ta ฦ™irฦ™irar jerin 2D, babu takamaiman ginanniyar ษ—akunan karatu da ake buฦ™ata. Koyaya, akwai wasu ษ—akunan karatu kamar NumPy, waษ—anda aka fi amfani dasu don aiki tare da tsararru da ฦ™ididdige ฦ™ididdiga. Sabanin haka, tsarin itertools yana ba da kayan aiki masu inganci iri-iri don sake maimaitawa akan masu haษ“akawa da ฦ™irฦ™irar sabbin masu haษ“akawa bisa waษ—anda suke da su.

Ta hanyar haษ—a waษ—annan da sauran ษ—akunan karatu da aka gina a cikin ayyukanku, zaku iya haษ“aka ฦ™warewar shirye-shiryenku na Python da ฦ™irฦ™irar kyawawan hanyoyin magance matsalolin gama gari da yawa.
