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 non-empty list of numbers Z. Write code to find the biggest number in the list.

Use: variables, loops, if[2]

Test Using:
Z = [1,2,3]
Z = [3,2,1,0]
Z = [81,36,64]
Assume you have a list of numbers A. Print the 9th element of A.

Use: variables[1]

Test Using:
A = [1,2,3,4,5,6,7,8,9,10]
Assume you have a list of letters B. Write code to count the number of times the letter "C" appears in the list.

Use: variables, loops, if[2]

Test Using:
B = []
B = ['C','a','z']
B = ['C','C','C']
Assume you have a list variable LIST of numbers. Use a variable to add the items in the list

Use: variables, loops[2]

Test Using:
LIST = [1]
LIST = [1,2,3,4,5,6,7,8,9]
LIST = [53,92,87]
Set two variables to different values then add them together

Use: variables[1]
A right angled triangle has 2 shorter sides of 9 and 9. Calculate the other side (the "hypotenuse").

Use: variables, sqrt()[2]
Use a loop to print 38 lines with the numbers from 1 to 38 and each number times 18, separated by a commma. For example, line 1 would be "1, 18", line 2 would be "2, 36",etc.

Use: variables, loops, str()[2]
Assume you have a list F with at least 2 elements. Create a new variable that is equal to the first two elements added together.

Use: variables[1]

Test Using:
F = ['a','b','c']
F = ['big','dog']
F = [20,80,20]
Print a list of strings, including a line number on each line

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