How to find the sum of even numbers from entered N numbers?

[Rajath]

my question here
n=int(input('Enter the number:'))
if(n<=0):
print('Enter a valid number')
else:
sum=0
count = 0
while(n>0):
for count in range (i % 2 ==0)
sum+=n
n-=1
print(sum)

my code here

n=int(input('Enter the number:'))
if(n<=0):
    print('Enter a valid number')
else:
    sum=0
    x = 0
    while(n>0):
        for x in range(0,n+1):
            if(x%2==0):
                sum=sum+x
                n=n-2
    print(sum)

end = int(input("Give me a number: "))
total = sum(range(0, end+1, 2))
print(total)

idk why you guys are trying to make it so complicated...
