Exercise 1

Using the following list, do the following:

1. Sort it in ascending order
2. In a print statement, referencing the list and its index numbers, print the lowest value and the highest value.

[15, 70, 15, 38, 49, 98, 62, 89, 2, 21, 40, 74, 36, 36, 65, 1, 55, 16, 24, 56]

Exercise 2 (1 Point):

Using the following list, do the following:

1. Iterate through each element in the list

2. Print out whether the element is positive or negative or zero on a new line for each element.

[-2, 1, -2, 7, -8, -5, 5, 10, -6, 7]

Exercise 3 (2 Points):

Create a new list using the range function, appending the values from the range function's output into the list.

The range function must:

1. Start at 1
2. Stop at 50
3. Skip every other number

Hint: Use either a for loop or a list comprehension

Exercise 4 (6 Points):

In this exercise, you will be required to do the following:

Take the following phrase: The only thing we have to fear is fear itself

1. Convert it to a list
2. Inspect each word in the list
   1. If the word in the list starts with a vowel (excluding y), then:
      1. add the letters "way" to the end of the word.
      2. EX: the word "and" would become "andway"
   2. If the word in the list does not start with a vowel (including y), then:
      1. take the first letter from the word and move it to the end of the word
      2. add to the end of the word, the letters "ay"
      3. EX: the word "money" would become "oneymay"
3. Append each modified word to a new list
4. convert the list to a string and print that string out
   1. HINT: use join()

So, the end result should be:

Hetay onlyway hingtay eway avehay otay earfay isway earfay itselfway
