Using Python to Count Even Numbers in List

June 28, 2022 Leave a Comment

To count the even numbers in a list in Python, the easiest way is with list comprehension and the Python len() function.

lst = [0, 4, 6, 9, 2, 3, 1]

count = len([num for num in lst if num % 2 == 0])

print(count)

#Output:
4

You can also use a loop to count the number of even numbers in a list in Python.

lst = [0, 4, 6, 9, 2, 3, 1]

def countEvens(l):
    count = 0
    for num in l:
        if num % 2 == 0:
            count = count + 1
    return count

print(countEvens(lst))

#Output:
4

When working with collections of data, the ability to easily summarize and get statistics about the collection is valuable.

One such case is if you want to count the even numbers in a list.

To count the even numbers in a list in Python, the easiest way is with list comprehension and the Python len() function. To get the even numbers, we just need to check if the number is even or odd.

Below is a simple example showing you how to count the number of even numbers in a list using Python.

lst = [0, 4, 6, 9, 2, 3, 1]

count = len([num for num in lst if num % 2 == 0])

print(count)

#Output:
4

Finding Sum of Even Numbers Using sum() in Python

You can use other functions to summarize collections of data in Python just like with length.

One example is if you want to find the sum of the even numbers of a list.

In this case, you can use the Python sum() function.

Below is an example showing you how to sum the even numbers of a list using Python.

lst = [0, 4, 6, 9, 2, 3, 1]

s = sum([num for num in lst if num % 2 == 0])

print(s)

#Output:
12

Get Count of Odd Numbers in List Using Python

If you want to go the other way and get the count of odd numbers in a list using Python, you can just make a simple adjustment to the code above.

When using % to check if the number is even or odd, for odd numbers we want inequality.

Below is an example showing you how to count the odd numbers in a list using Python.

lst = [0, 4, 6, 9, 2, 3, 1]

count = len([num for num in lst if num % 2 != 0])

print(count)

#Output:
3
