Exercise 7.3.4: Find the Error

5 points

Let's Go!

In this exercise, you will try to identify which of two lines will cause an error. The two lines look like this:

my_string[0] = "H" my_string = "H" + my_string[1:]

Each line is an attempt to change the string from "hello!" to "Hello!". One of them does this in an acceptable way, and the other one causes an error.

Before you run the program, see if you can predict which of the two lines is incorrect. Test your guess by commenting out what you think is the incorrect line and running the program!

5 points

Let's Go!

You are in a spelling bee! Dont worry - even if your spelling is a little rusty, you have Python to help you out.

Using a for loop, add some code to this program that prints each letter of the given word. Each letter should be on its own line.

And since you are so excited to be in this spelling bee, you should add an exclamation mark after each letter.

The output should look like this:

Your word is: eggplant. e! g! g! p! l! a! n! t!
