Answers should be legal Python code, including indentation. Use the underscore _ to show a space.
Special functions: print(), range(), sqrt(), str()
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 = 62
Assume you have a list variable LIST. Count the number of items in LIST.

Use: loops, variables[2]

Test Using:
LIST = ['a','b','c']
LIST = [1,2,3,4,5,6]
LIST = []
Assume you have a list of letters F. Write code to count the number of times the letter "c" appears in the list.

Use: variables, loops, if[2]

Test Using:
F = []
F = ['c','a','z']
F = ['c','c','c']
Assume you have a list of numbers Y. Write code to count the number of times the number 90 appears in the list.

Use: variables, loops, if[2]

Test Using:
Y = [90]
Y = [0,90,-1,90,99,90]
Y = [67,97,44]
Assume you have a non-empty list of numbers Y. Create a new variable that is equal all the numbers in Y multiplied together.

Use: variables, loops[2]

Test Using:
Y = [1,1]
Y = [1,2,3,4,5]
Y = [52,91,74]
Assume you have a list variable LIST. Count the number of items in LIST and print the result.

Use: loops, variables[2]

Test Using:
LIST = ['a','b','c']
LIST = [1,2,3,4,5,6]
LIST = []
Assume you have a list of numbers Q. Print the 5th element of Q.

Use: variables[1]

Test Using:
Q = [1,2,3,4,5,6,7,8,9,10]
Assume you have a non-empty list F. Create a new variable that is equal to the first element in the list.

Use: variables[1]

Test Using:
F = [1]
F = ['a','b','c']
F = [27,31,72]
Do the sum 40 + 83 and print the result

Use: [1]
