Question

Using the Python program:

a/ Write a program that adds all numbers from 1 to 100 to a list (in order). Then remove the multiples of 3 from the list. Print the remaining values.

b/ Write a program that initializes a list with ten random integers from 1 to 100. Then remove the multiples of 3 and 5 from the list. Print the remaining values.

Please show your work and explain. Thanks

SOLUTION

a)

list =[i for i in range(1,101)] #creating a list containing numbers from 1 to 100
print(list) #printing the created list

#for loop to traverse the list and remove multiples of 3
for i in list:
  if(i%3 == 0): #condition to check if the element in the list is a multiple of 3 or not
      list.remove(i) #if yes we remove that element
print("\nList after removing multiples of 3:")
print(list)

OUTPUT

b)

import random #importing random package
list = [] #declaring empty list
for i in range(0,10): #for loop to fill list with random numbers between 1 and 100
    n = random.randint(1,100)
    list.append(n)
print(list)

for i in list: #for loop to remove multiples of 3 and 5 from the list
  if(i%3 == 0 or i%5 == 0):
      list.remove(i)
print("\nList after removing multiples of 3 and 5:")
print(list)
