Separate odd and even numbers in a list into two different lists:

In this tutorial, we will discuss about separating odd and even numbers in a list into two different list.

When you divide a number by two and if the balance is zero, it is an even number.

When a number is divided by two with a remaining balance of 1, then it’s an odd number.

Example of even number 2,4,6,8,…..

Example of odd number 1,3,5,7,…..

Here, we will use a modular operator to display odd or even numbersFirst.

if n%2==0, n is a even number

if n%2==1, n is a odd number

Python program to separate odd and even number in a list — Separate odd and even number in a list

Program 1

Approach

To begin with, the user can allocate a length of the list of numbers using input() function.
Then, it is initialized by a list called “NumberList=[] ” which doen’t have any numbers.
Next, “for loop” is used to insert the numbers into the list.
The”For loop” is then used to append each number to the list NumberList=[].
Next, create two empty list: evenList=[] and oddList=[] for storage of even and odd numbers following separating from the initial mixed list
then, another “for loop” checks whether the number is even or odd in the list through a modular operator.
finally, odd and even numbers are displayed into the different list

if n%2==0, n is an even number, it is saved into an evenList=[]

if n%2==1, n is an odd number, it is saved into an oddList=[]

Program

numbers=[]  #Create a empty list for store number from user input
num=int(input("Enter number of elements: "))
for i in range(1,num+1):
    listElements=int(input("Enter telement %d: "%i))
    numbers.append(listElements)

evenList=[]  #list for store even number
oddList=[] #list for store odd number

for j in numbers:
    if j%2==0:
        evenList.append(j)
    else:
        oddList.append(j)

print("Even number list: ",evenList)#display separated even number list
print("Odd number list: ",oddList) #display separated odd number list

When the above code is executed, it produces the following results

Enter number of elements: 7
Enter telement 1: 25
Enter telement 2: 46
Enter telement 3: 67
Enter telement 4: 78
Enter telement 5: 89
Enter telement 6: 90
Enter telement 7: 87
Even number list: [46, 78, 90]
Odd number list:  [25, 67, 89, 87]
