To demonstrate use of slicing in string using python programming.

#Slicing in String

print("SI = Starting index; EI = Ending index")

nrStr = "I am Narendra Rajpoot."

print("Length of Streing : ",len(nrStr))

print("String : ",nrStr)

print("Charcter at index 3 : ",nrStr[3])

print("String [SI = 3; EI = end of the sting] : ",nrStr[3:])

print("String [SI = 3; EI = 13] : ",nrStr[3:13])

print("String [SI = 0; EI = 10] ",nrStr[:10])

print("String [SI = 3; EI = 12; charcter differnce = 2]",nrStr[3:12:2])
