Answer 2

sum=0 # I too a black variable sum, so that we can put the sum of the natural numbers in it.

for i in range(1,8): # for loop from 1,8. This will give me the value of natural numbers one by one.

      sum+=i # When the sum is added to the natural number it'll change it's value.

      print("The sum of nutural numbers till {} is {}.".format(i,sum)) # This will print the sum one by one.

print("\nThe sum of all the natural numbers from 1 to 7 is {}.".format(sum)) # This will print the last value of sum.
