Natural numbers:

As the name specifies, a natural number is the number that occurs commonly and obviously in the nature. It is a whole, non-negative number.

Some mathematicians think that a natural number must contain 0 and some don't believe this theory. So, a list of natural number can be defined as:   

N= {0, 1, 2, 3, 4, .... and so on}  

N= {1, 2, 3, 4, .... and so on}

num = int(input("Enter a number: "))  
  
if num < 0:  
   print("Enter a positive number")  
else:  
   sum = 0  
   # use while loop to iterate un till zero  
   while(num > 0):  
       sum += num  
       num -= 1  
   print("The sum is",sum)

This example shows the sum of the first 100 positive numbers (0-100)
