[whatloop]

1 2 3 4 5 6 7 8 9 10 11 12

def summation(n):         total = 0         for count in range(1,n + 1):                 total += count         return total   def main():         n = int(input('Enter the number of terms : '))         total = summation(n)         print('Sum of first', n, 'positive integers:  ' ,total) if__name__=='__main__':         main()

THE ERROR MESSAGE IS

Error:
Error(s), warning(s):

Indentation should be 4-space not 8 and i trow in f-string.

1 2 3 4 5 6 7 8 9 10

def summation(n):     return sum(range(1, n+1))   def main():     n = int(input('Enter the number of terms : '))     total = summation(n)     print(f'Sum of first {n} positive integers: {total}')   if __name__=='__main__':         main()
