Assume you have two non-empty lists of numbers VAR and Z. Create a new variable that is equal to the first element of each list added together.

Use: variables[1]

Test Using:
VAR = [1], Z = [1]
VAR = [1,2,3], Z = [3,2,1]
VAR = [41,85,1], Z = [64,26,67]

Create a list containing 3 colors

Use: variables[1]

Assume you have a variable S that is the length of the side of a square. Calculate another variable that is equal to the area of the square.

Use: variables[2]

Test Using:
S = 87

Assume you have a list of names, F. Write code to count the number of times the name "Julie" appears in the list.

Use: variables, loops, if[2]

Test Using:
F = []
F = ['Julie']
F = ['Julie','Jenny','Felix','Julie']

Create a list containing 2 colors

Use: variables[1]

Print a list of strings, including a line number on each line

Use: variables, loops, str()[2]

Assume you have a list of letters VAR. Write code to count the number of times the letter "a" appears in the list.

Use: variables, loops, if[2]

Test Using:
VAR = []
VAR = ['a','a','z']
VAR = ['a','a','a']

Assume you have a non-empty list of scores VAR for your math class. Calculate the average of the scores.

Use: variables, loops[3]

Test Using:
VAR = [10]
VAR = [1,2,3,4,5]
VAR = [24,9,69]
