Inkinga enkulu ehlobene neskripthi se-cmd Python esihlala sivulekile ukuthi singabangela ukuvuza kwememori nezinye izinkinga zensiza yesistimu. Uma iskripthi singavalwanga kahle, singaqhubeka sisebenza ngemuva futhi sisebenzise izinsiza zesistimu, okungaholela ekwehleni kokusebenza nokungazinzi. Ukwengeza, uma iskripthi siqukethe noma iyiphi ikhodi enonya, ingase isetshenziselwe ukuxhaphaza isistimu noma kubangele ezinye izinkinga zokuphepha.
import time
while True:
print("Python script is still running")
time.sleep(60)
1. isikhathi sokungenisa: Lesi sitatimende singenisa kwamanye amazwe imojula yesikhathi, esivumela ukuthi sifinyelele imisebenzi ehlobene nesikhathi nosuku.
2. ngenkathi Iqiniso: Lo mugqa udala iluphu engapheli ezosebenza ize iphuke isitatimende sekhefu noma kwenzeke iphutha.
3. phrinta(“Iskripthi se-Python sisasebenza”): Lo mugqa uphrinta umlayezo othi “Iskripthi se-Python sisasebenza” njalo uma iluphu isebenza.
4. isikhathi.ukulala(60): Lo mugqa umisa iluphu imizuzwana engama-60 ngaphambi kokuthi iqalise futhi, okusivumela ukuthi sihlole ukuthi ingabe iskripthi sethu sisasebenza njalo ngeminithi ngaphandle kokuthi sikwenze mathupha isikhathi ngasinye.
Iyini i-CMD kuPython
I-CMD kuPython iyisixhumi esibonakalayo somugqa womyalo (CLI) sokusebenzisa imibhalo yePython. Ivumela abasebenzisi ukuthi bathayiphe imiyalo ngqo kumhumushi, obese ekhipha ikhodi bese ebuyisela imiphumela. I-CMD ingasetshenziselwa ukudala, ukulungisa iphutha, nokusebenzisa izinhlelo zePython kusuka kulayini womyalo. Iphinde inikeze ukufinyelela emisebenzini eminingi eyakhelwe ngaphakathi namamojula atholakala kuPython.
Ngenza kanjani ukuthi iskripthi sePython sihlale sivulekile
Kunezindlela ezimbalwa ezahlukahlukene zokwenza iskripthi sePython sihlale sivulekile kuPython.
1. Sebenzisa iluphu engapheli: Iluphu engapheli iyiluphu egijima unomphela futhi engapheli. Ungasebenzisa lokhu ukuze ugcine iskripthi sakho sisebenza kuze kube yilapho umsebenzisi ephuma mathupha kuso. Ukuze udale iluphu engapheli, ungasebenzisa isitatimende esithi "ngenkathi Iqiniso". Lokhu kuzobangela ukuthi ikhodi engaphakathi kweluphu isebenze ngokuqhubekayo ize ikhishwe mathupha ngumsebenzisi noma kuhlangatshezwane nesinye isimo.
2. Sebenzisa isibali sikhathi: Ungasebenzisa futhi isibali sikhathi ukuze ugcine umbhalo wakho usebenza isikhathi esithile ngaphambi kokuba uphume ngokuzenzakalelayo. Ukuze wenze lokhu, ungasebenzisa imojula "yesikhathi" kuPython futhi usethe isibali sikhathi usebenzisa umsebenzi waso othi "sleep()" othatha ingxabano ecacisa ukuthi ufuna ukuthi iskripthi sakho sihlale sivulekile isikhathi esingakanani (ngemizuzwana).
3. Sebenzisa okokufaka okuvela kumsebenzisi: Okokugcina, ungase futhi ucele okokufaka kumsebenzisi futhi ugcine umbhalo wakho usebenza baze bafake okuthile okuqondile okumtshela ukuthi aphume (isb, ukuthayipha “phuma”). Ukuze wenze lokhu, ungasebenzisa umsebenzi owakhelwe ngaphakathi we-Python othi “input()” othatha impikiswano ecacisa ukuthi imuphi umlayezo okufanele uboniswe lapho ucela okokufaka kumsebenzisi (isb, “Thayipha ukuphuma ukuze uyeke:”). Bese uhlola ukuthi abakufakile kuyahambisana yini nalokho okufanele kusetshenziswe njengomyalo wokuphuma futhi uma kunjalo, phuma ku-loop yakho bese uvala uhlelo lwakho ngokufanele.
