Slice the Word

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)

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.

Mastering string manipulation is essential, and it will greatly improve your skills in handling data structures.

Use slicing to extract the word "puppy" and assign it to the variable puppy
Use slicing to extract the word "nestling" and assign it to the variable nestling

Make sure to use only the techniques covered in this chapter. 😇
