Question 70

Question

Please write a program to output a random even number between 0 and 10 inclusive using random module and list comprehension.

Hints

Use random.choice() to a random element from a list.

Main author's Solution: Python 2

1li = [2,4,6,8]
2import random
3print random.choice([i for i in range(11) if i%2==0])

My Solution: Python 3

1import random
2resp = [i for i in range(0,11,2)]
3print(random.choice(resp))

Question 71

Question

Please write a program to output a random number, which is divisible by 5 and 7, between 10 and 150 inclusive using random module and list comprehension.

Hints

Use random.choice() to a random element from a list.

Main author's Solution: Python 2

1import random
2print random.choice([i for i in range(10,151) if i%5==0 and i%7==0])

My Solution: Python 3

1import random
2resp = [i for i in range(10,151) if i % 35 == 0 ]
3print(random.choice(resp))

Question 72

Question

Please write a program to generate a list with 5 random numbers between 100 and 200 inclusive.

Hints

Use random.sample() to generate a list of random values.

Main author's Solution: Python 2

1
2import random
3print random.sample(range(100,201), 5)

My Solution: Python 3

1import random
2resp = random.sample(range(100,201),5)
3print(resp)

Question 73

Question

Please write a program to randomly generate a list with 5 even numbers between 100 and 200 inclusive.

Main author's Solution: Python 2

1
2import random
3print random.sample([i for i in range(100,201) if i%2==0], 5)

My Solution: Python 3

1import random
2resp = random.sample(range(100,201,2),5)
3print(resp)

Question 74

Question

Please write a program to randomly generate a list with 5 numbers, which are divisible by 5 and 7 , between 1 and 1000 inclusive.

Hints

1
2import random
3print random.sample([i for i in range(1,1001) if i%5==0 and i%7==0], 5)

My Solution: Python 3

1import random
2lst = [i for i in range(1,1001) if i%35 == 0]
3resp = random.sample(lst,5)
4print(resp)
