For example if I take a user input of any integer like 12 I have to get the total of 1+2+3……. till the end

Please if you understand my question help me out

Answer 1

You can use the range(start,end) function to get the required range of numbers and then use sum() function to get the sum of all numbers in that range.

Ex. sum(range(0,11)).
It will give the sum 0+1+2....+10

Answer 2

a = 0
for i in range(int(input())):a+=i
print(a)

This should be working.

Answer 3

Easy:

a = int(input(' :-> '))
s = -~a/2*a
s0 = sum(range(a+1))
print(s,s0)

num = int(input("Enter digit: "))
print(sum(range(1, num+1)))

def add(num):
sum = 0
for val in range(1, num+1):
sum += int(val)
return sum

print(add(13))

Answer 5

Use sum(range(start, end)) built-in function, imo.

Answer 6

You can write a for loop using range function from 1 to n + 1 (n is the number whose sum from 1 to it is to be found) and sum it over that range. You need to initialize your sum at 0.
