How to do Find the error in 7.3.4 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!
