Yakagadziriswa: rename duplicates mune runyorwa python

Kupazve mazita akapetwa mune runyorwa kunogona kuve dambudziko rakaoma kugadzirisa nekuti zvinoda kuti iwe uone zvakapetwa uye wozofunga kuti ungavatumidza sei. Izvi zvinogona kunyanya kunetsa kana rondedzero yacho iine zvinhu zvakawanda kana kuti zvinhu zvakaoma kunzwisisa. Pamusoro pezvo, kutumidza mazita akadzokororwa kungada kuti ugadzirise zvimwe zvikamu zvekodhi yako zvinotsamira pamazita ekutanga ezvinhu kuitira kuti varambe vachishanda nemazvo.

Zvinyorwa muPython

Rondedzero muPython ndeimwe yeanonyanya kushandiswa data zvimiro. Izvo zvinoshandiswa kuchengetedza muunganidzwa wezvinhu, izvo zvinogona kuva zvemhando ipi neipi, kusanganisira mamwe mazita. Rondedzero inoshanduka, zvichireva kuti inogona kushandurwa mushure mekunge yagadzirwa. Ivo zvakare vanotsigira mashandiro akaita se indexing, slicing, uye concatenation.

Kugadzira runyorwa muPython, unoshandisa masikweya mabhureki uye unoparadzanisa chinhu chimwe nechimwe necomma:

my_list = [1, 2, 3]

Iwe unogona kuwana zvinhu zvega murunyorwa uchishandisa index yavo:
my_list[0] # inodzosa 1
my_list[1] # inodzosa 2
my_list[2] # inodzosa 3

Iwe unogona zvakare kushandisa ma indices asina kunaka kuwana zvinhu kubva kumagumo echinyorwa:

my_list[-1] # inodzosa 3 (chinhu chekupedzisira)

Iwe unogona kuwedzera zvinhu pane rondedzero uchishandisa iyo append() nzira:

my_list.append(4) # inowedzera 4 kusvika kumagumo echinyorwa

Unogona kubvisa zvinhu kubva pane rondedzero uchishandisa bvisa () kana pop () nzira:

my_list.remove(3) # inobvisa 3 kubva pakurongwa

my_list.pop(2) # inobvisa uye inodzosa 2 (chinhu chechitatu) kubva pakurongwa

Rename zvakapetwa mune runyorwa muPython

Rename duplicates mune rondedzero muPython ibasa rakajairika kana uchibata nemazita. Zvinosanganisira kutsiva zvinhu zvakapetwa murunyorwa zvine maukoshi akasiyana. Izvi zvinogona kuitwa uchishandisa set() basa, iro rinobvisa zvese zvakapetwa zvinhu kubva pane rondedzero uye kudzosa runyoro rutsva rune zvinhu zvakasarudzika. Iyo set () basa rinogona zvakare kushandiswa kutumidza zita rakapetwa nekupa iyo mepu yemaitiro ekare kune hutsva hutsika. Semuyenzaniso, kana uine runyorwa rwenhamba uye uchida kutsiva zvese zvakapetwa nemasikweya azvo, unogona kushandisa kodhi inotevera:

# Gadzira duramanzwi risina chinhu
mepu = {}

# Iterate pamusoro peiyo yekutanga runyorwa
chechinhu chiri mu_list:
# Tarisa kana chinhu chiripo muduramazwi
kana chinhu chisiri mumepu:
# Kana zvisiri, wedzera kune duramazwi uye ugovane sikweya yayo sekukosha
mepu[chinhu] = chinhu * chinhu

# Gadzira rondedzero isina chinhu yemhedzisiro
result_list = []

# Dzokorora pamusoro pekutanga runyorwa zvakare uye tsiva chinhu chimwe nechimwe nechikwere kubva muduramazwi re ini mune yangu_list: result_list.append(mapping[i])

# Dhinda mhedzisiro inodhinda (mhedzisiro_list)
