Exercises
- Questions 1-11, assume you have the following following representation of the string
schoolName = "Washington-Lee H.S."
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 |
W | a | s | h | i | n | g | t | o | n | - | L | e | e | H | . | S | . |
What is:
schoolName[0]
schoolName[6]
schoolName[3:8]
schoolName[:10]
schoolName[15:]
schoolName[19]
len(schoolName)
len("")
- What range specifies “Lee”?
- If you had a variable called sample, how could you return the last character, even if you didn't know its length?
- Create a string "The quick brown fox jumps 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
- Use the string variable s from Question 11. Create a loop that prints out every letter in the variable s
- Use the string variable s from Question 11. Create a loop that prints out every letter in s backwards starting from the end.
- Use the string variable s from Question 11. Create a loop that prints out every other letter in s starting from the beginning
