Python program to get input n and calculate the sum of even numbers till n Input: 5 Output: 6(2+4)

n=int(input("Enter n value:")) sum=0 for i in range(2,n+1,2): sum+=i print(sum)

For Statement is used to execute the sequence of intruction repeatedly. Range() method gives list of elements, here range() method gives list which has 2,4,6... to n or n-1. for statement executes the instructions iteratively and for takes the elements one by one as value of i in sequential manner. so it adds even numbers.
