# Creating a string

print("Elements till 7th element from last: ", string_1)
string_2 = string[-7:-4]
print("Elements from index -7 to -5:",string_2)

print("String in reverse order: ", string_3)

Task

You have such a string programming. You have to carry out these steps:

  1. print elements sliced till 8th element from last(as a result you have to get: pro)
  2. print elements sliced from index -8 to -3(as a result you have to get: grammi)
  3. print elements in reverse using slice operation(as a result you have to get: gnimmargorp).
