In this chapter, we will create a method which will return the value which needs to be added to the total of all the numbers within a list to get the closest prime number from that total. A prime number is a number which can only be divided by one and itself. 1 is not a prime number. The below program will add one to the sum of all the numbers within a list until it reaches the closest prime number from that total, it then will return the value which needs to be added to reach that prime status.

def minimum_number(numbers): total = sum(numbers) n=0 notprime = True if(total == 1): return 1 elif(total == 2): return 0 else: while(notprime): for i in range(2,total): if(total%i == 0): notprime = True break else: notprime = False if(notprime == True): total+=1 n+=1 else: return n

As you can see we will use the notprime flag to control the while loop until we get the answer which we need.
