Inkinga enkulu ngezindlela zokusesha kuPython ukuthi azilungiselelwanga isivinini. Lokhu kunganciphisa uhlelo lwakho kakhulu.
The search method in python can be used to find a substring in a given string. This method returns the index of the first occurrence of the substring in the string. If the substring is not found, it returns -1.
Example:
str = "Hello world"
print str.search("world")
Output: 6
Ukucinga
Ku-Python, ungasebenzisa umsebenzi wokusesha owakhelwe ngaphakathi ukuze uthole izinto ezithile ngokulandelana kwedatha. Umsebenzi wokusesha uthatha izimpikiswano ezimbili: ukulandelana kokusesha kanye negama elingukhiye noma iphethini okufanele uyibheke.
Ukuze useshele zonke izinto ezinegama elithi “ikati” kuzo, ungasebenzisa ikhodi elandelayo:
phrinta(“Isesha 'ikati'…”) sesha = “ikati” phrinta(“Kutholwe izinto ezingu-%d.” % (len(sesha)))
Okukhiphayo le khodi kuzoba:
Isesha 'ikati'… Ithole izinto ezi-5.
izindlela
Kunezindlela eziningi ezahlukene kuPython. Ezinye zezindlela ezivame kakhulu zibalwe ngezansi.
def: Lona umsebenzi othatha impikiswano eyodwa noma ngaphezulu. Umsebenzi uzobuyisela inani.
phrinta: Lokhu kuphrinta iyunithi yezinhlamvu yombhalo esikrinini.
uma: Lokhu kuhlola uma isimo siyiqiniso. Uma kunjalo, ikhodi engaphakathi kwe-if block izokwenziwa, ngaphandle kwalokho ngeke isetshenziswe.
