Nyika yehurongwa inogona kuzara nezvinoshamisa, kunyanya kana tikasangana nezvikanganiso zvatisati tamboona. Imwe mhosho yakadai inogona kusangana nevagadziri vePython ndeye "% 27str% 27 chinhu hachina hunhu %27remove% 27" kukanganisa. Kukanganisa uku kunoitika kana uchiedza kushandisa nzira ye "bvisa" pane chinhu chetambo, chisiri chinoshanda muPython. Muchikamu chino, tichaongorora chikonzero chekukanganisa uku uye nekupa mhinduro, pamwe chete netsanangudzo-nhanho-nhanho yekodhi. Pamusoro pezvo, tichakurukura nezvemaraibhurari akakodzera uye mabasa anogona kubatsira kudzivirira nyaya dzakafanana mune ramangwana.
Chikonzero chikuru che "% 27str% 27 chinhu chisina hunhu %27remove% 27" kukanganisa kuri pakuti muPython, tambo hadzichinjike. Izvi zvinoreva kuti kana tambo yagadzirwa, haigoni kuchinjwa. Iyo "bvisa" nzira haipo kune tambo zvinhu, sezvo inonyanya kushandiswa pamazita. Kuti tigadzirise nyaya iyi, tinoda kutsvaga imwe nzira yekuzadzisa mashandiro atinoda, sekushandisa nzira yeku “tsiva” kana kunyora manzwisisiro.
string_example = "Hello, world!" character_to_remove = "l" new_string = string_example.replace(character_to_remove, "") print(new_string)
Mune snippet yekodhi iri pamusoro, takashandisa nzira ye "tsiva" kubvisa chimiro chakataurwa kubva patambo. Nzira ye "tsiva" inotora nharo mbiri: yekutanga ndiyo substring inofanira kutsiviwa, uye yechipiri ndiyo itsva substring ichashandiswa. Nekupfuura tambo isina chinhu senharo yechipiri, isu tinobvisa zvinobudirira hunhu hunodiwa.
Rondedzera Manzwisisiro: Imwe nzira
Imwe nzira yekubvisa hunhu kubva patambo ndeye kushandisa rondedzero kunzwisisa. Iyi nzira inosanganisira kupenengura nemavara ega ega mutambo uye kungoiwedzera kune tambo itsva kana isingaenderane nechimiro chinobviswa. Heino maitiro ezvingaitwa:
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)
Mumuenzaniso uyu, takashandisa runyoro rwekunzwisisa kugadzira runyoro rutsva rune mavara ese asingaenderane neanofanira kubviswa. Isu takazoshandisa nzira ye "join" kushandura rondedzero kuti ive tambo.
Python String Nzira uye Maraibhurari
Python inopa yakapfuma seti ye tambo nzira izvo zvinogona kubatsira neakasiyana tambo manipulation mabasa. Dzimwe dzenzira dzinowanzo shandiswa dzinosanganisira "kubvisa", "kupatsanura", "kumusoro", uye "pasi". Uyezve, Python's re (regular expression) raibhurari inogona kushandiswa kune yakanyanya kuoma maitiro ekufananidza uye kugadzirisa mabasa.
import re string_example = "Hello, world!" pattern_to_remove = "l" new_string = re.sub(pattern_to_remove, "", string_example) print(new_string)
Mune kodhi snippet iri pamusoro, takashandisa nzira ye "sub" kubva kuraibhurari yekubvisa zvese zvinoitika zveimwe patani kubva patambo. Izvi zvinogona kunyanya kubatsira kana uchibata nemaitiro akaomarara kana akawanda mavara kuti abvise.
Muchidimbu, "% 27str% 27 chinhu hachina chimiro % 27remove% 27" kukanganisa kunokonzerwa nekuedza kushandisa nzira ye "kubvisa" pachinhu chetambo, iyo isingatsigirwi muPython nekuda kwechimiro chisingachinji chetambo. Dzimwe nzira, dzakadai sekushandisa nzira ye "tsiva" kana nzwisiso yemazita, inogona kushandiswa kubvisa mavara kubva patambo. Zvakare, kunzwisisa Python yakavakirwa-mukati tambo nzira uye re raibhurari inogona kubatsira mukubata zvine hunyanzvi mabasa akasiyana siyana ekugadzira tambo.
