In the preceding chapter, we discussed the method for extracting a particular character from a string. However, what procedures can we employ to obtain a particular substring with a consecutive sequence of characters? The most straightforward approach is to employ a technique called slicing.

This operation allows us to get not only one symbol, but a combination of symbols per operation. Take a look at the syntax:


              
123

            
string = "Extract the word kitten"
kitten = string[17:23]
print(kitten)
copy

The syntax is string[starting_index : ending_index], but try to double check the indexation for the word kitten.

k has an index of 17, but the n character has an index of 22, not 23.

Why was 23 written?

The solution is straightforward. The ending index is exclusive, meaning that when we write 23, Python does not include this index but considers the one immediately before it.

Proficiency in handling strings is of paramount importance. Furthermore, it will significantly enhance your ability to manipulate data structures.

  1. Select the word puppy using slicing.
  2. Select the word nestling using slicing.
  3. Print the variable puppy.
  4. Print the variable nestling.
