See more:

l=[]
sum,i=0,0
for x in range(101):
if x%10==0:
l.append(x)
print(l)
while i<101:
sum=sum+l[i]
i=i+1
print("Sum is:",sum)

What I have tried:

l=[]
sum,i=0,0
for x in range(101):
if x%10==0:
l.append(x)
print(l)
while i<101:
sum=sum+l[i]
i=i+1
print("Sum is:",sum)

I'm guessing the sum doesn't work? the code should sum what in the list and not loop 101 times because it will cause out of range error.

Python

l=[]
sum,i=0,0
for x in range(101):
	if x % 10 == 0:
    		l.append(x)
		print(l)
            
for i in xrange(1,len(l)):
	sum=sum+l[i]
    
print("Sum is:",sum)

Output
[0]
[0, 10]
[0, 10, 20]
[0, 10, 20, 30]
[0, 10, 20, 30, 40]
[0, 10, 20, 30, 40, 50]
[0, 10, 20, 30, 40, 50, 60]
[0, 10, 20, 30, 40, 50, 60, 70]
[0, 10, 20, 30, 40, 50, 60, 70, 80]
[0, 10, 20, 30, 40, 50, 60, 70, 80, 90]
[0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
('Sum is:', 550)

Solution 2

Python

l=[]
for x in range(10,101,10):
  l.append(x)
  print(l)

print("Sum is:", sum(l))

Or, if you need just the sum:

Python

limit = 101
n = (limit - limit % 10) / 10
sum = n * (n + 1) * 5
print("Sum: ", sum)
