Answers should be legal Python code, including indentation. Use the underscore _ to show a space.

Special functions: print(), range(), sqrt(), str()

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

Use: variables[1]

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

A right angled triangle has a hypotenuse (longest side, opposite the right angle) of 10 and another side of 7. Calculate the length of the missing side.

Use: variables, sqrt()[2]

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']

Use a loop to print the sum of the numbers from 9 to 22

Use: variables, loops[2]

Print each number from 4 to 19

Use: loops[2]

Create two strings and join them together with a space between

Use: variables[1]

Assume you have a list of numbers X. Write code to count the number of times the number 47 appears in the list.

Use: variables, loops, if[2]

Test Using:
X = [47]
X = [0,47,-1,47,99,47]
X = [62,58,68]

Assume you have 2 lists of numbers with 10 elements each: B and Z. Add the 7th elements of the lists together.

Use: variables[1]

Test Using:
B = [1,2,3,...,10], Z = [1,2,3,...,10]

Assume you have 2 variables S and T that are equal to the sides of a rectangle. Calculate another variable that is equal to the area of the rectangle.

Use: variables[2]

Test Using:
S = 88, T = 89
