Print the even and odd integers of the integer in a separate line in python

In this program we create a user input list and the elements are mixture of odd and even elements. Our task is to split these list into two list. One contains odd number of element and another is even number of elements.

Example

Input: [1, 2, 3, 4, 5, 9, 8, 6]
Output
Even lists: [2, 4, 8, 6]
Odd lists: [1, 3, 5, 9]

Algorithm

Step 1 : create a user input list.
Step 2 : take two empty list one for odd and another for even.
Step 3 : then traverse each element in the main list.
Step 4 : every element is divided by 2, if remainder is 0 then it’s even number and add to the even list, otherwise its odd number and add to the odd list.

Example Code

# Python code to split into even and odd lists 
# Funtion to split 
def splitevenodd(A): 
   evenlist = [] 
   oddlist = [] 
   for i in A: 
      if (i % 2 == 0): 
         evenlist.append(i) 
      else: 
         oddlist.append(i) 
   print("Even lists:", evenlist) 
   print("Odd lists:", oddlist) 
  
# Driver Code 
A=list()
n=int(input("Enter the size of the First List ::"))
print("Enter the Element of First  List ::")
for i in range(int(n)):
   k=int(input(""))
   A.append(k)
splitevenodd(A) 

Output

Enter the size of the First List :: 8
Enter the Element of First  List ::
1
2
3
4
5
9
8
6
Even lists: [2, 4, 8, 6]
Odd lists: [1, 3, 5, 9]

I was asked this question in a tcs codevita interview. Given an array

a = [1,2,3,4,5,6,7,8,9,10]

you have to write a one line code in Python such that you get 2 different array/lists where one will contain odd numbers and the other will contain even numbers. i.e one list

odd = [1,3,5,7,9]

and other list

even =[2,4,6,8,10]

I was not able to write this code in one line. Can anyone tell me how to solve this in one line?

You can use two list comprehensions in one line:

odd, even = [el for el in a if el % 2==1], [el for el in a if el % 2==0]

print(odd, even)
#([1, 3, 5, 7, 9], [2, 4, 6, 8, 10])

List comprehension holds the answer. But rather than comprehend on both even and odd list construction, pop one kind (even in this case) from you original list a and put in it's list and what you have left in a will be the other kind (odd):

>>> even, odd = [a.pop(index) for index, item in enumerate(a) if item % 2 == 0], a
>>> print(even,odd)
[2, 4, 6, 8, 10] [1, 3, 5, 7, 9]

You can slice the list with a step of 2:

odd, even = a[::2], a[1::2]

Using key,to get in a single list

print(sorted(j,key=lambda x:(x%2,-a.index(x))))

Using list comprehension:    

def evenodd(myl): 
       evenlist = [num for num in myl if num % 2 == 0] 
       oddlist = [num for num in myl if num % 2 == 1]  
       print("Even numbers:", evenlist) 
       print("Odd numbers:", oddlist) 
      
    mylist=list()
    n=int(input("Enter the size of the  List:"))
    print("Enter the numbers:")
    for i in range(int(n)):
       k=int(input(""))
       mylist.append(k)
    evenodd(mylist)
