• Dictionary Comprehension

• Enumerate

• Length

• Int

• List

Now-a-days, most of the components of the String module are already built into python however, it still has several constant values which can be useful, such as:

string.ascii_uppercase

import string

string.ascii_uppercase

'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

1. Write a function that takes the length of a side of a square as an argument and returns the area of the square.

# A:

---

2. Write a function that takes the heigth and width of a triangle and returns the area.

# A:

---

3. Write a function that takes a string as an argument and returns a tuple consisting of two elements:

• A list of all the characters in the string.

• A count of the number of characters in the string.

# A:

---

4. Write a function that takes two integers, passed as strings, and returns the sum, difference, and product as a tuple (all values as integers).

# A:

---

5. Write a function that takes a list as the argument and returns a tuple consisting of two elements:

• A list with the items in reverse order.

• A list of the items in the original list that have an odd index.

# A:

Challenge Problem: Write a function that returns the score for a word. The score of the word is the sum of the scores of its letters. Each letter's score is equal to it's position in the alphabet.

So, for example:

• A = 1, B = 2, C = 3, D = 4, E = 5

• abe = 8 = (1 + 2 + 5)

Hint: The string library has a property ascii_lowercase that can save some typing here.
