Python | print list after removing ODD numbers

Here, we are going to implement a python program that will print the list after removing ODD numbers. By IncludeHelp Last updated : June 25, 2023

Given a list, and we have to print the list after removing the ODD numbers in Python.

Example

Input:
list = [11, 22, 33, 44, 55]

Output:
list after removing ODD numbers
list = [22, 44]

Logic

• Traverse each number in the list by using for...in loop.
• Check the condition i.e. checks number is divisible by 2 or not – to check ODD, number must not be divisible by 2.
• If number is not divisible by 2 i.e. ODD number from the list, use list.remove() method.

Python program to print list after removing ODD numbers

# list with EVEN and ODD numbers
list = [11, 22, 33, 44, 55]

# print original list
print("Original list:")
print(list)

# loop to traverse each element in the list
# and, remove elements
# which are ODD (not divisible by 2)
for i in list:
    if i % 2 != 0:
        list.remove(i)

# print list after removing ODD elements
print("List after removing ODD numbers:")
print(list)

Output

Original list:
[11, 22, 33, 44, 55]
List after removing ODD numbers:
[22, 44]

Using filter() and lambda expression

You can also remove the ODD numbers from a list by using the filter() function and lambda expression. Consider the below program -

# list with EVEN and ODD numbers
list1 = [11, 22, 33, 44, 55]

# print original list
print("Original list:")
print(list1)

# removing ODD numbers
# using filter() & lambda expression
newlist = list(filter(lambda x: (x % 2 == 0), list1))

# print list after removing ODD numbers
print("List after removing ODD numbers:")
print(newlist)

Output

Original list:
[11, 22, 33, 44, 55]
List after removing ODD numbers:
[22, 44]

Using list comprehension

By using the list comprehension create a new list of EVEN numbers. In this way, you can get a list without ODD numbers.

# list with EVEN and ODD numbers
list1 = [11, 22, 33, 44, 55]

# print original list
print("Original list:")
print(list1)

# removing ODD numbers
# using list comprehension
# create a list of EVEN numbers, in this way
# you will have a list without ODD numbers
newlist = [x for x in list1 if x % 2 == 0]

# print list after removing EVEN elements
print("List after removing EVEN numbers:")
print(newlist)

Output

Original list:
[11, 22, 33, 44, 55]
List after removing EVEN numbers:
[22, 44]
