sum is a function and count is a variable. I have used sum as a variable in previous reply but we should not use any identifier as a variable.

This is the solution to sum integer value 1 to N.

So if N is 10 then range(1, N + 1) will give 55 but you are adding N to this range output so total means N will be N = N + 55 = 10 + 55 = 65.

But you have printed N - count so output will be 65 - 10 = 55.

But your this solution is confusing for new learner so here is easy solution

sum1 = 0

for i in range(1, N + 1):
sum1 = sum1 + i

print (sum1)

because range(1, N + 1) means range (1, 11) will return a list with values (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) and the sum of this list will be 55.

Try this in code playground

l = range(1, 11)

print (list(l))
print (sum(l))

Answer 4

that's a weird solution to sum up the integers from 1 to N ^^

Answer 5

If N is 10 how range (1,N+1) will give 55? plz briefly explain I am time....

Answer 6

Is sum a variable?
Is count a variable?
