Question 1

pick a random number

Answer 1

random. randint(1, 6)

random. randrange(6) + 1 -> random number between 6 numbers(0, 1, 2, 3, 4, 5); if (6) + 1 -> (1, 2, 3, 4, 5, 6)

Question 2

a combination of functions, combined for a specific purpose

Answer 2

module

Question 3

Answer 3

random.randint()

Question 4

Answer 5

branching

Question 6

Answer 8

block

Question 9

Answer 9

1, the first one where the condition is True (or if none evaluate to True then the else statement)

Question 10

Answer 10

elif or else clauses

Question 11

a value compared to other values in a condition

Answer 11

sentry variable (needs to be initialised before the loop)

Answer 12

Tracing

Question 13

which number /and string evaluate to False?

Answer 13
