Exercises

1. Complete the following representation of the string schoolName="Washington Lee H.S."

00	01	02	03	04	05	06	07	08	09	10	11	12	13	14	15	16	17	18
W	a														H	.	S	.

What is:

1. schoolName[0]
2. schoolName[6]
3. schoolName[3]=”X”
4. schoolName[3:8]
5. schoolName[:10]
6. schoolName[15:]
7. schoolName[19]
8. len(schoolName)
9. len(“”)
10. What range specifies “Lee”?
11. What expression returns the last character of string ‘sample’?
12. Create a string "The quick brown fox jumped over the lazy dog." in a variable s
    • Print out the first letter in s using the brackets (e.g. s[NUM])
    • Print out the letter "q" using s and the index 4
    • Print out the letter "x" using s and the corresponding index
    • Using string slicing, print out the word "brown"
    • Using string slicing, print out the word "lazy"
    • Using string slicing, print out starting at the word "jumped" through the end of the string
13. Use the string variable s from Question 1. Create a loop that prints out every letter in the variable s
14. Use the string variable s from Question 1. Create a loop that prints out every letter in s backwards starting from the end.
15. Use the string variable s from Question 1. Create a loop that prints out every other letter in s starting from the beginning
