Let’s simplify things by making the letters in our word lowercase.

the_string = "Hello"
the_string = the_string.lower()

The .lower() function does not modify the string itself, it simply returns a lowercase-version. In the example above, we store the result back into the same variable.

We also need to grab the first letter of the word.

first_letter  = the_string[0]
second_letter = the_string[1]
third_letter  = the_string[2]

Remember that we start counting from zero, not one, so we access the first letter by asking for [0].
