Introduction :
In this tutorial, we will learn how to find the product of all odd and even numbers in a list. The program will take the list values as input from the user and print out the product. With this program, you will learn how to use a for loop,if-else condition and how to take inputs in python.
Python program :
Python program to find the product of all odd and even numbers in an user-provided list :
#1
my_list = []
#2
total = int(input("How many numbers you want to add to the list : "))
#3
for i in range(0, total):
my_list.append(int(input("Enter : ")))
print("You have entered: ", my_list)
#4
odd_product = 1
even_product = 1
#5
for i in my_list:
if(i % 2 == 0):
even_product *= i
else:
odd_product *= i
#6
print("Product of all odd numbers: ", odd_product)
print("Product of all even numbers: ", even_product)
Explanation :
The commented numbers in the above program denote the step numbers below :
-
Create one empty list my_list.
-
Ask the user to enter the total count of numbers to add to the list. Read and store it in total variable.
-
Run one for loop and read each element as an input from the user. Print the list to the user.
-
Create two variables to hold the product of all odd and even numbers.
-
Iterate through each element of my_list using a for-in loop. For each element, check if the current number is even or odd. If it is even, multiply it with even_product. Else, multiply it with odd_product.
-
Finally, print out the products.
Sample Output :
How many numbers you want to add to the list : 5
Enter : 2
Enter : 4
Enter : 9
Enter : 10
Enter : 5
You have entered: [2, 4, 9, 10, 5]
Product of all odd numbers: 45
Product of all even numbers: 80
