Umhlaba wezinhlelo ungagcwala izimanga, ikakhulukazi uma sihlangabezana namaphutha esingakaze siwabone ngaphambilini. Iphutha elilodwa elinjalo abathuthukisi be-Python abangase bahlangane nalo ukuthi "%27str%27 into ayinayo imfanelo %27remove%27" iphutha. Leli phutha lenzeka lapho uzama ukusebenzisa indlela "yokususa" entweni yochungechunge, okungewona umsebenzi ovumelekile kuPython. Kulesi sihloko, sizohlola imbangela yaleli phutha futhi sinikeze isixazululo, kanye nencazelo yesinyathelo ngesinyathelo yekhodi. Ukwengeza, sizoxoxa ngamalabhulali afanelekile nemisebenzi engasiza ukuvimbela izinkinga ezifanayo ngokuzayo.
Umsuka wephutha elithi “%27str%27 alinasibaluli %27remove%27” iseqinisweni lokuthi kuPython, izintambo aziguquleki. Lokhu kusho ukuthi uma iyunithi yezinhlamvu isidaliwe, ayikwazi ukushintshwa. Indlela "yokususa" ayikho ezintweni zochungechunge, njengoba isetshenziselwa ikakhulukazi uhlu. Ukuze sixazulule le nkinga, sidinga ukuthola enye indlela yokufeza umsebenzi esiwufunayo, njengokusebenzisa indlela "yokubuyisela" noma uhlu lokuqonda.
string_example = "Hello, world!" character_to_remove = "l" new_string = string_example.replace(character_to_remove, "") print(new_string)
Kumazwibela ekhodi ngenhla, sisebenzise indlela "yokubuyisela" ukuze sisuse uhlamvu olushiwo kuyunithi yezinhlamvu. Indlela "yokubuyisela" ithatha ama-agumenti amabili: eyokuqala iwuchungechunge oluncane oluzoshintshwa, kanti eyesibili iwuchungechunge oluncane olusha oluzosetshenziswa. Ngokudlulisa iyunithi yezinhlamvu engenalutho njengengxabano yesibili, sisusa ngempumelelo uhlamvu olufunayo.
Uhlu Lokuqondisisa: Indlela Ehlukile
Enye indlela yokukhipha uhlamvu oluthile ocingweni ukusebenzisa ukuqonda kohlu. Le ndlela ihlanganisa ukuxhuma kuhlamvu ngalunye kuyunithi yezinhlamvu futhi iyengeze kuphela entanjeni entsha uma ingahambisani nohlamvu oluzokhishwa. Nansi indlela engenziwa ngayo:
string_example = "Hello, world!" character_to_remove = "l" new_string = "".join([char for char in string_example if char != character_to_remove]) print(new_string)
Kulesi sibonelo, sisebenzise ukuqonda kohlu ukuze sakhe uhlu olusha oluqukethe zonke izinhlamvu ezingafani nohlamvu oluzosuswa. Sibe sesisebenzisa indlela "yokujoyina" ukuze siguqule uhlu lube yiyunithi yezinhlamvu.
Izindlela Zezintambo Ze-Python Nemitapo Yolwazi
I-Python inikeza isethi ecebile ye izindlela zentambo engasiza ngemisebenzi ehlukahlukene yokukhohlisa izintambo. Ezinye zezindlela ezisetshenziswa kakhulu zihlanganisa “ukuhlubula”, “ukuhlukanisa”, “okungaphezulu”, kanye “nokuphansi”. Ngaphezu kwalokho, i-Python's re (inkulumo evamile) umtapo wolwazi ingasetshenziselwa imisebenzi eyinkimbinkimbi yokufanisa kanye nokuguqula.
import re string_example = "Hello, world!" pattern_to_remove = "l" new_string = re.sub(pattern_to_remove, "", string_example) print(new_string)
Kumazwibela ekhodi ngenhla, sisebenzise indlela "encane" kusukela kulabhulali kabusha ukuze sisuse konke ukuvela kwephethini ethile kuyunithi yezinhlamvu. Lokhu kungaba usizo ikakhulukazi uma usebenzisana namaphethini ayinkimbinkimbi noma izinhlamvu eziningi ongazisusa.
Kafushane, into ethi “%27str%27 ayinaso isibaluli %27remove%27” iphutha libangelwa ukuzama ukusebenzisa indlela “yokususa” entweni yeyunithi yezinhlamvu, engasekelwe ku-Python ngenxa yokungaguquleki kweyunithi yezinhlamvu. Ezinye izindlela, ezifana nokusebenzisa indlela "yokubuyisela" noma ukuqonda kohlu, kungasetshenziswa ukususa izinhlamvu kuyunithi yezinhlamvu. Ngaphezu kwalokho, ukuqonda izindlela zezintambo ezakhelwe ngaphakathi zePython kanye nomtapo wolwazi kungasiza ekuphatheni kahle imisebenzi ehlukahlukene yokukhohlisa izintambo.
