Which term describes a pre-written collection of code that a program can bring in to add extra features, such as the one that creates random numbers?
Library
What is the name for creating values in a program that cannot be predicted and are different each time the program runs?
Random number generation
What is meant by random.randint(1, 6)?
A call that returns a whole number from 1 to 6, including both ends
What is meant by storing the value of random.randint(1, 6) in a variable?
Keeping the number so the same value can be used again later
Which line must appear at the top of a Python program so that random.randint can be used?
Import random
What values does random.random() return?
A real number from 0.0 up to but not including 1.0
A program needs to store a random real number from 5.0 up to but not including 10.0 in a variable called value. Which line should it use?
Value = 5 + random.random() * 5
A game rolls two separate dice with random.randint(1, 6) each and adds them. How does this differ from one call of random.randint(2, 12)?
Totals near 7 are more likely with two separate dice
Which line gives a value that could represent the two possible outcomes of a coin toss?
Coin = random.randint(0, 1)
A program calls random.randint(1, 6) but does not start with import random. What happens?
A NameError is reported when the line is run
A program picks six lottery numbers using six separate calls of random.randint(1, 49). Why is this not suitable for a real lottery?
The same number can be picked more than once
A program stores random.randint(1, 100) in a variable and then prints the value doubled. What could the output be?
A whole number from 2 to 200
Which of these programs needs to produce values that are different each time it runs?
A program that rolls dice for a game
How many times should import random appear in a program that creates random numbers in several places?
Once, at the top of the program
This program rolls two dice. Which totals can be printed?
Any whole number from 2 to 12
Why must a program import the random library before random.randint can be used?
The function is held in the library, not built in
