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 list of numbers Q. Print the 10th element of Q.

Use: variables[1]

Test Using:
Q = [1,2,3,4,5,6,7,8,9,10]

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

Use: variables[2]

Test Using:
S = 17

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

Use: variables, loops, if[2]

Test Using:
A = []
A = ['C','a','z']
A = ['C','C','C']

Use a loop to multiply the numbers from 1 to 21

Use: variables, loops[2]

Assume you have a list of numbers VAR. Write code to add up the numbers in the list that are bigger than 12

Use: variables, loops, if[3]

Test Using:
VAR = []
VAR = [5,6,7,8,9,10,11,12,13,14,15]
VAR = [95,51,64]

Assume you have a list of numbers B. Create a new variable that is equal to sum of all the numbers in B.

Use: variables, loops[2]

Test Using:
B = []
B = [1,1]
B = [84,22,80]

A right angled triangle has 2 shorter sides of 6 and 7. Calculate the other side (the "hypotenuse").

Use: variables, sqrt()[2]

Assume you have 2 lists of numbers with 19 elements each: Y and B. Add the 10th elements of the lists together.

Use: variables[1]

Test Using:
Y = [1,2,3,...,19], B = [1,2,3,...,19]
