How do you make sure your while loop does not turn into an infinite loop?
Make sure you increment a variable and/or cause the condition to eventually become false
How do you call a function?
function_name()
Which aggregate uses parenthesis and which uses curly brackets?
-not including dictionary
parentheses: tuples
curly brackets: sets
Using the % symbol the following will equal
47 % 3
what is 2, the remainder of 3 * 15?
What will print?

b = False
if a and b:
print("Hello World")
else:
if not(a and b):
print("Hi World")

return x*y*z
print(“The answer is “, x*y*z)
There is something after the return statement; Return statements should always be last!
list = [ [1,2,3], [4,5,6], [7,8,9] ]

def square(x):
y = x * x
return y
print(square(square(2)))
