# Python Program to Calculate Sum of Even Numbers

Write a Python Program to Calculate Sum of Even Numbers from 1 to N using While Loop and For Loop with an example.

## Python Program to Calculate Sum of Even Numbers from 1 to N using For Loop

This Python program allows the user to enter the maximum limit value. Next, Python is going to calculate the sum of even numbers from 1 to that user-entered value.

In this example, we are using Python For Loop to keep the number between 1 and maximum value.

TIP: I suggest you refer to Python Even Numbers from 1 to N article to understand the logic behind printing Even numbers in Python.

```# Python Program to Calculate Sum of Even Numbers from 1 to N

maximum = int(input(" Please Enter the Maximum Value : "))
total = 0

for number in range(1, maximum+1):
if(number % 2 == 0):
print("{0}".format(number))
total = total + number

print("The Sum of Even Numbers from 1 to {0} = {1}".format(number, total))```

Python sum of even numbers output

`````` Please Enter the Maximum Value : 15
2
4
6
8
10
12
14
The Sum of Even Numbers from 1 to 15 = 56``````

## Python Program to Calculate Sum of Even Numbers from 1 to N without If Statement

This Python sum of even numbers program is the same as above. But we altered the Python For Loop to remove If block.

```# Python Program to Calculate Sum of Even Numbers from 1 to N

maximum = int(input(" Please Enter the Maximum Value : "))
total = 0

for number in range(2, maximum + 1, 2):
print("{0}".format(number))
total = total + number

print("The Sum of Even Numbers from 1 to {0} = {1}".format(number, total))```

Python sum of even numbers using a for loop output

`````` Please Enter the Maximum Value : 12
2
4
6
8
10
12
The Sum of Even Numbers from 1 to 12 = 42``````

## Python Program to find Sum of Even Numbers using While Loop

In this Python sum of even numbers example, we replaced the For Loop with While Loop.

```# Python Program to Calculate Sum of Even Numbers from 1 to N

maximum = int(input(" Please Enter the Maximum Value : "))
total = 0
number = 1

while number <= maximum:
if(number % 2 == 0):
print("{0}".format(number))
total = total + number
number = number + 1

print("The Sum of Even Numbers from 1 to N = {0}".format(total))```

Python sum of even numbers using a while loop output

`````` Please Enter the Maximum Value : 20
2
4
6
8
10
12
14
16
18
20
The Sum of Even Numbers from 1 to N = 110``````

## Python Program to find Sum of Even Numbers from 1 to 100

This Python program allows users to enter Minimum and maximum value. Next, Python calculates the sum of even numbers from Minimum to the maximum value.

```# Python Program to Calculate Sum of Even Numbers from 1 to 100

minimum = int(input(" Please Enter the Minimum Value : "))
maximum = int(input(" Please Enter the Maximum Value : "))
total = 0

for number in range(minimum, maximum+1):
if(number % 2 == 0):
print("{0}".format(number))
total = total + number

print("The Sum of Even Numbers from {0} to {1} = {2}".format(minimum, number, total))```
