Because your previous lesson, 9.Move it on Back, tells you to set
new_word = word + first + pyg?
The final output is to have your first letter after the other letters and before the pyg.
So, you made a variable specifically for your first letter,
first = word.
Now, you have to put that in
new_word = word + first + pyg.
Let's say your word you inputted was "cat", the console will print
catcay. The last step is to remove that first letter so it prints
atcay which is the desired output according to the lesson.
In order to do that, you will create a slice,
new_word = new_word[1:len(new_word)] after
new_word = word + first + pyg. This slice tells the program to start from index 1 of the new word all the way to the end. Note: The first letter is at index 0. And that's how you get
