Q474 - Modules
Look at the code below:
- import random
- #
- # Insert lines of code here.
- #
- print(a, b, c)
Which lines of code would you insert so that it is possible for the program
to output the following result:
6 82 0
-
A
- a = random.randint(0, 100)
- b = random.choice((0, 100, 3))
- c = random.randrange(10, 100, 3)
-
B
- a = random.randint(0, 100)
- b = random.randrange(10, 100, 3)
- c = random.choice((0, 100, 3))
-
C
- a = random.randrange(10, 100, 3)
- b = random.randint(0, 100)
- c = random.choice((0, 100, 3))
-
D
- a = random.choice((0, 100, 3))
- b = random.randrange(10, 100, 3)
- c = random.randint(0, 100)
Reveal correct answer
Correct answer: B
Explanation
Topics: import random randint() randrange() choice()
Try it yourself:
- import random
- a = random.randint(0, 100)
- b = random.randrange(10, 100, 3)
- c = random.choice((0, 100, 3))
- print(a, b, c) # e.g. 6 82 0
- print(random.randint(0, 100)) # e.g. 0, 1, 2, ... 98, 99, 100
- print(random.randrange(10, 100, 3)) # e.g. 10, 13, 16, ... 91, 94, 97
- print(random.choice((0, 100, 3))) # e.g. 0, 100, 3
Explanation:
randint(0, 100) will return a number
between 0 (inclusive) and 100 (inclusive).
randrange(10, 100, 3) will return a number between
10 (inclusive) and 100 (EXCLUSIVE)
with a step of three: 10, 13, 16, ... , 79, 82, 85, ...
choice((0, 100, 3)) will return one element of the tuple (0, 100, 3)
Q474 (Please refer to this number, if you want to write me about this question.)
A. This choice is incorrect because it assigns the result of random.choice() function to variable 'b', which may not generate an integer value between 10 and 100 with a step of 3 as required. The order of functions used for 'a', 'b', and 'c' does not match the expected output of 6, 82, and 0.
B. This choice is correct because it uses the random.randint() function to generate a random integer between 0 and 100 for variable 'a', random.randrange() function to generate a random integer between 10 and 100 with a step of 3 for variable 'b', and random.choice() function to select a random element from the tuple (0, 100, 3) for variable 'c'. This combination of functions ensures that the values assigned to 'a', 'b', and 'c' are within the specified ranges.
C. This choice is incorrect because it assigns the result of random.randrange() function to variable 'a', which may not generate an integer value between 0 and 100 as required. The order of functions used for 'a', 'b', and 'c' does not match the expected output of 6, 82, and 0.
D. This choice is incorrect because it assigns the result of random.choice() function to variable 'a', which may not generate an integer value between 0 and 100 as required. Additionally, the order of functions used for 'a', 'b', and 'c' does not match the expected output of 6, 82, and 0.
