Ingxaki ephambili enxulumene neskripthi se-cmd Python ehlala ivulekile kukuba inokubangela ukuvuza kwememori kunye neminye imiba yemithombo yenkqubo. Ukuba iskripthi asivalwanga ngokufanelekileyo, sinokuqhubeka nokusebenza ngasemva kwaye sisebenzise izixhobo zenkqubo, ezinokubangela ukunciphisa ukusebenza kunye nokungazinzi. Ukongeza, ukuba iskripthi siqulethe nayiphi na ikhowudi engalunganga, ingasetyenziselwa ukuxhaphaza inkqubo okanye kubangele eminye imiba yokhuseleko.
import time
while True:
print("Python script is still running")
time.sleep(60)
1. ixesha lokungenisa: Le ngxelo ingenisa imodyuli yexesha, esivumela ukuba sifikelele kwimisebenzi enxulumene nexesha kunye nomhla.
2. ngelixa Yinyani: Lo mgca wenza i-loop engapheliyo eya kusebenza de yaphulwe yintetho yekhefu okanye kwenzeke impazamo.
3. print(“Iskripthi sePython sisasebenza”): Lo mgca uprinta umyalezo “Iskripthi sePython sisasebenza” ngalo lonke ixesha iluphu isebenza.
4. ixesha.sleep (60): Lo mgca unqumamisa i-loop imizuzwana engama-60 ngaphambi kokuba iphinde isebenze, ivumela ukuba sijonge ukuba iskripthi sethu sisasebenza ngomzuzu ngamnye ngaphandle kokwenza oko ngesandla ngexesha ngalinye.
Yintoni iCMD kwiPython
I-CMD kwiPython lujongano lwelayini yomyalelo (CLI) yokusebenzisa imibhalo yePython. Ivumela abasebenzisi ukuba bachwetheze imiyalelo ngokuthe ngqo kwitoliki, ethi ke iphumeze ikhowudi kwaye ibuyisele iziphumo. I-CMD ingasetyenziselwa ukwenza, ukulungisa iimpazamo, kunye nokuqhuba iinkqubo zePython ukusuka kumgca womyalelo. Ikwabonelela ngokufikelela kwimisebenzi emininzi eyakhelweyo kunye neemodyuli ezikhoyo kwiPython.
Ndenza njani ukuba iskripthi sePython sihlale sivulekile
Kukho iindlela ezimbalwa ezahlukeneyo zokwenza iskripthi sePython sihlale sivulekile kwiPython.
1. Sebenzisa i-loop engapheliyo: I-loop engapheliyo yi-loop ehamba ngokungenasiphelo kwaye ayinakuphela. Ungasebenzisa oku ukugcina iskripthi sakho sisebenza de umsebenzisi asikhuphe ngesandla. Ukwenza iluphu engapheliyo, ungasebenzisa inkcazo "ngelixa Yinyani". Oku kuya kubangela ukuba ikhowudi engaphakathi kwilophu iqhube ngokuqhubekayo de ikhutshwe ngesandla ngumsebenzisi okanye enye imeko idibene.
2. Sebenzisa isibali-xesha: Ungasebenzisa kwakhona isibali-xesha ukugcina iskripthi sakho sisebenza kangangexesha elithile phambi kokuba uphume ngokuzenzekelayo. Ukwenza oku, ungasebenzisa imodyuli "yexesha" kwiPython kwaye usete isibali-xesha usebenzisa "ukulala ()" umsebenzi othatha ingxabano echaza ukuba ufuna ixesha elingakanani ukuba iskripthi sakho sihlale sivulekile (ngemizuzwana).
3. Sebenzisa igalelo lomsebenzisi: Okokugqibela, unokuphinda ucele igalelo kumsebenzisi kwaye ugcine iskripthi sakho sisebenza de bafake into ethile eyixelela ukuba iphume (umzekelo, ukuchwetheza “phuma”). Ukwenza oku, ungasebenzisa iPython eyakhelwe-ngaphakathi “igalelo ()” umsebenzi othatha ingxabano echaza ukuba ngowuphi umyalezo omawuboniswe xa ucela igalelo kumsebenzisi (umzekelo, “Thayipha ukuphuma ukuze uphume”). Emva koko, khangela ukuba oko bakungenisileyo kuyahambelana noko kufuneka kusetyenziswe njengomyalelo wokuphuma kwaye ukuba kunjalo, phuma kwi-loop yakho kwaye uphelise inkqubo yakho ngokufanelekileyo.
