For school we have to create a program in python in which we generate a given number of random numbers and you can choose by what multiplication. I tried this code (which will show my list is empty) but I’m wondering if there is a specific function for this in python because I cant seem to find out how to do it.
from random import randint
list = []
aantal = int(input("Hoeveel random getallen wilt u? "))
veelvoud = int(input("Welke veelvoud? "))
for i in range(aantal):
getal = randint(1, 100)
if getal % veelvoud == 0:
list.append(getal)
else:
i -= 1
print(list)
thanks in advance and sorry for the language it’s dutch.
>Solution :
Here’s a different way to approach the problem:
-
Request user input for the number of random numbers, and the step
-
Create an empty list
-
While the list contains less elements than the number requested, generate random numbers between 1 and 100
-
Check if the random number is a multiple of the step, and if so, add it to the list
from random import randint
number = int(input("How many random numbers to generate?: "))
step = int(input("Multiple of which number? : "))
nums_list = []
while len(nums_list) < number:
rand = randint(1, 100)
if rand % step != 0:
continue
else:
nums.append(rand)
print(nums_list)
An even more efficient way would be to generate random numbers in a way such that the number will always be a multiple of the step:
from random import randint
number = int(input("How many random numbers to generate?: "))
step = int(input("Multiple of which number? : "))
# The highest number that can be multiplied with the step to
# produce a multiple of the step less than 100
max_rand = floor(100/step)
nums_list = []
for _ in range(number):
rand = randint(1, max_rand) * step
nums_list.append(rand)
print(nums_list)
