Write A Python Program To Count The Number Of Even And Odd Numbers From A Series Of Numbers

Write A Python Program To Count The Number Of Even And Odd Numbers From A Series Of Numbers

In this Python example post, you will learn to write a python program to check if a number is odd or even from a series of numbers. We will show you the different examples so that you can choose your preferred solution.

Example 1:

1. Write A Python Program To Count The Number Of Even And Odd Numbers From A Series Of Numbers

In the following code, you can see the python program to count the number of even and odd numbers from the given series of numbers.

Numbers =(1,2,3,4,5,6,7,8,9)
count_odd_num =0
count_even_num =0
for x in numbers:
      if not x % 2:
    	     count_even_num+=1
        else:
    	     count_odd_num+=1
print("Number of even numbers :",count_even_num)
print("Number of odd numbers :",count_odd_num)

Example 2:

2. Python program to Count Even And Odd numbers in a List

In this other example, you can see the example of a python program to count even and odd numbers in a list.

list1 = [10, 21, 4, 45, 66, 93, 1] even_count, odd_count = 0, 0
# iterating each number in list
for num in list1:
# checking condition
if num % 2 == 0:
even_count += 1
else:
odd_count += 1
print("Even numbers in the list: ", even_count)
print("Odd numbers in the list: ", odd_count)

Output:

Even numbers in the list:  3
Odd numbers in the list:  4

Example 3:

3. Python program to Count Even And Odd numbers in a List using While loop

Write a program in python to count even and odd numbers using while loop.

# list of numbers
list1 = [10, 21, 4, 45, 66, 93, 11]

even_count, odd_count = 0, 0
num = 0

# using while loop
while(num < len(list1)):

# checking condition
if list1[num] % 2 == 0:
even_count += 1
else:
odd_count += 1

# increment num
num += 1

print("Even numbers in the list: ", even_count)
print("Odd numbers in the list: ", odd_count)

Example 4 :

4. Python program to Count Even And Odd numbers in a List Using Python Lambda Expressions

Write a program in python to count even and odd numbers using python lambda expressions.

# list of numbers
list1 = [10, 21, 4, 45, 66, 93, 11]

odd_count = len(list(filter(lambda x: (x%2 != 0) , list1)))

# we can also do len(list1) - odd_count
even_count = len(list(filter(lambda x: (x%2 == 0) , list1)))

print("Even numbers in the list: ", even_count)
print("Odd numbers in the list: ", odd_count)

Example 5:

5. Python program to Count Even And Odd numbers in a List Using List Comprehension

Write a program in python to count even and odd numbers in list using list comprehension

# Python program to print odd Numbers in a List
 
# list of numbers
list1 = [10, 21, 4, 45, 66, 93, 11]
 
only_odd = [num for num in list1 if num % 2 == 1]
odd_count = len(only_odd)
 
print("Even numbers in the list: ", len(list1) - odd_count)
print("Odd numbers in the list: ", odd_count)

Example 6:

6. Python program to Count Even And Odd numbers in a List Using Recursion

if (n < 2):
return (n % 2 == 0) 
return (check(n - 2)) 
n=int(input("Enter number:")) 
if(check(n)==True): 
print("Number is even!") 
else: print("Number is odd!")
