Python: Calculate Average of odd and even in a list using loops

In this post, we will realize about the title of  “Python: Calculate Average of odd and even in a list using loops”.

In this article, we will explore how to calculate the average of odd and even numbers in a list. The list will be generated using numbers, and we will use both for-loops and while-loops to achieve this.

Here’s a Python program that calculates the average of odd and even numbers

Program 1

In this code, we calculate the average of odd and even numbers using for-loop

# Python code to calculate Average of odd and even numbers in a list
#input list
NumList=[1,2,3,4,5,6,7,8,9,10]
#initialize sums
even_Sum=0
even_Count=0
odd_Sum=0
odd_Count=0

#Loop through the list
for num in NumList:
    if num%2==0:
         even_Sum+=num  #Add to even sum
         even_Count+=1
    else:
          odd_Sum+=num  #Add to odd sum
          odd_Count+=1

#calculate average
even_Avg=even_Sum/even_Count if even_Count !=0 else 0
odd_Avg=odd_Sum/odd_Count if odd_Count !=0 else 0

    
    #print the result
    
print(f"Average of even numbers:{even_Avg}")
print(f"Average of odd numbers:{odd_Avg}")

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

Average of even numbers:6.0
Average of odd numbers:5.0

 

Explanation

• Define a list with numbers
• Initialise variables as even_Sum=0, even_Count=0, odd_Sum=0,odd_Count=0
• Separate odd and even numbers and adding one by one to find the odd sum and even sum
• Calculate the average if odd sum and even sum using sum/count
• Print the result average of odd sum and even sum

 

Program 2

In this code, we calculate the average of odd and even numbers using user input with while-loop

# Python code to calculate Average of odd and even numbers in a list
#input list
NumList=[11,12,13,14,15,16,17,18,19,20]
#initialize variables
even_Sum=0
even_Count=0
odd_Sum=0
odd_Count=0
index=0

#Loop through the list
while index <len(NumList):
    if NumList[index]%2==0:
         even_Sum+=NumList[index]  #Add to even sum
         even_Count+=1
    else:
          odd_Sum+=NumList[index] #Add to odd sum
          odd_Count+=1
    index+=1

#calculate average
even_Avg=even_Sum/even_Count if even_Count !=0 else 0
odd_Avg=odd_Sum/odd_Count if odd_Count !=0 else 0

    
    #print the result
    
print(f"Average of even numbers:{even_Avg}")
print(f"Average of odd numbers:{odd_Avg}")

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

Average of even numbers:16.0
Average of odd numbers:15.0

 

Explanation

• Define a list with numbers
• Initialise variables as even_Sum=0, even_Count=0, odd_Sum=0,odd_Count=0
• Separate odd and even numbers and adding one by one to find the odd sum and even sum
• Calculate the average if odd sum and even sum using sum/count
• Print the result average of odd sum and even sum
